Static and dynamic strength analysis of vibrating snow shovel and the latest snow removal mechanical technology
Wang Xishan
I focused on the research and development of snow removal equipment in 2000, and I was the inventor of "vibration" snow removal shovel. The research and design of snow removal machinery and equipment must first ensure the availability and performance of snow removal machinery and equipment. This paper analyzes the static strength and dynamic strength analysis of vibrating snow shovel by professors Liu Yibin, Liu Yi-bin, Liu Yi-bin and Lu Yi-lu of Jilin University, and briefly explains the necessary structure of snow removal machinery and equipment in the design. I tried my best to make the language easy to understand, guided the correct thinking in the research and development field of snow removal machinery and equipment, and promoted the development of products.
The Static and Dynamic Strength Analysis of Vibrating Snow Shovel written by Liu Yibin, Liu Yibin, Liu Yibin and Lu Lu of Jilin University (referred to as "Analysis") originated in the spring of 20 1 1. Entrusted by an enterprise in baishan city, Jilin University improved the production technology of vibrating snow shovel for this enterprise, which was far from the actual situation. The "vibration", "ice and snow crushing" and "automatic obstacle crossing" mentioned in the abstract of Analysis and the "snow shovel can crush and remove compacted ice and snow" mentioned in the text snapshot are not practical. The concept and exposition of "analysis" itself is wrong. Although its content deviates from reality, I will dialysis it in order to play a correct guiding role in the research and development of ice and snow removal machinery, enrich the theoretical and practical basis in research and development, and better serve the people and society.
At present, there is no mechanical equipment at home and abroad that can really clear the ice on the road area. One of the reasons is that snow removal machinery developed relatively late compared with other machinery, and there is no special requirement for countries to remove the ice formed on the road surface. The second reason is that the formation of ice is a typical material tri-state, that is, liquid water cools and forms a solid state on the road surface, so the affinity between ice and road surface is very strong, and the hardness of ice and asphalt is basically the same. It is difficult to peel off objects with the same hardness by mechanical force without damaging the road surface. I have made a breakthrough in effective deicing on the road surface, and the products will be available soon.
According to different national conditions, different countries in the world have different snow removal machinery and equipment, which have practical snow removal effects. As for the winter road snow in China, it has certain particularity, and the compacted snow accounts for more than 70%. Compacted snow has a very strong adhesion on the road surface and a certain affinity. At present, there is no mechanical equipment with stable performance to remove compacted snow at home and abroad. There are different protrusions on urban pavement and expressway pavement in China, which forces all kinds of snow removal machinery and equipment to have good avoidance. In this respect, all snow removal machinery is not ideal, even snow removal machinery with avoidance performance can not meet the requirements. All kinds of snow removal machinery and equipment developed and produced by Jilin Jieying have been verified by the market, and the removal effect of compacted snow, ice-snow mixture (snow is not completely frozen) and natural snow is very good. When you meet a protrusion on the road, you can pass by yourself, and the servo reset will continue to work after passing. On the one hand, it is worth learning and learning from the industry, and it is worth restructuring and expanding production to serve the society.
2. Static and dynamic strength analysis of Liu Yibin, Liu Yibin, Liu Yibin and Liu Lu of Jilin University. The "vibration", "ice breaking" and "automatic obstacle crossing" mentioned in the analysis summary are really unrealistic, and deicing cannot be realized at all.
1, "vibration" dialysis machinery and equipment have vibration performance, which does have certain effects, but it is by no means "vibration". Vibration and "vibration" are not the same concept. Vibration refers to the overall active vibration of mechanical equipment, and shovel blade is the executive structure of snow shovel. The shovel blade has the function of vibration frequency exceeding 5000 times/minute, and forms a certain angle with the road surface, which can play a good role in removing ice and snow. After years of research and development, I have finished this vibrating shovel and it will come out soon. This vibrating shovel can remove ice and snow. "Vibration" refers to a form of active reciprocating motion of mechanical equipment. "Vibration" should have certain restrictions on all kinds of mechanical equipment, and the frequency of "vibration" should not be too high, otherwise the mechanical equipment will produce * * * vibration, which will make the equipment unable to work. In the snow removal machinery and equipment, if the included angle between the shovel blade and the road surface is suitable for snow removal, the structural mass of the "vibrating" connector is 300kg, the "vibrating" reciprocating is 8mm, and the frequency is 600 times /min. The whole snow removal machinery does not produce * * * vibration. According to this set of data, the linear speed of the shovel blade is 4800mm/min. If the working speed of the whole snow removal machinery and equipment is set to 50000mm/min(3km/h), the blade of the snow shovel does not realize reciprocating "vibration", that is, "vibration" does not realize the performance of "breaking ice and snow" in snow removal operation, so it is unrealistic to say that the snow shovel can impact and break compacted ice and snow and remove it. The concept of performance is wrong, and the content in its analysis is of course divorced from reality.
2. "Automatic obstacle crossing" cannot be described clearly. Snow removal performance is very important, which determines whether the snow removal shovel can remove snow. Jilin University copied the snow shovel structure produced by Jilin Baishan Enterprise and applied for a utility model patent (20 122027 1647.4). The main structure described is the same as the national patent (20 1020 1565438) applied by others as early as 2065438. The snow shovel with this structure can automatically cross the road surface to protrude objects during the slow snow removal operation, but it cannot be automatically reset after crossing, which requires the operator's servo reset. Its description of "automatic obstacle crossing" is very misleading to the industry and users' real understanding of performance. My self-designed fully automatic obstacle-crossing reset compaction snow shovel will soon face the market.
Three. Basic requirements for structural design of snow removal machinery and equipment
1, the present situation of snow removal machinery in China, the cities that snow in winter basically snow while the vehicles are constantly driving on the roads, so the roads in cities are mainly compacted snow. At present, there is no stable snow removal machinery and equipment except the snow removal shovel produced by Jilin Jieying. Due to the unreasonable design of the included angle between the shovel blade and the road surface and the insufficient design of obstacle crossing, all kinds of snow shovels are basically limited by downward pressure during operation, which makes the snow shovels unable to achieve snow removal performance. Due to the fast consumption of wearing parts and insufficient structural design, the whole snow removal mobile machinery is unstable. Because the market demand of snow removal machinery is large, there is a certain profit space, and it can be realized by general manufacturing methods, which urges units or individuals with certain conditions to produce and sell with one idea, which makes the market of snow removal machinery and equipment chaotic.
2. Basic requirements of snow removal machinery and equipment in structural design. The design of obstacle-crossing structure and the angle between shovel blade and road surface directly affect the performance of snow removal machinery. According to many years' experiments and research on various kinds of snow, the snow shovel is the best choice for snow removal on urban roads. The included angle between the shovel blade and the road surface is 30-50 according to different road conditions and snow conditions, and the shovel blade is the best design after crossing obstacles. The hardness of compacted snow is very different from that of general hardened pavement. According to the mechanical analysis of manual snow removal with shovel, the shovel blade must have three points of force, so that the shovel blade can peel the compacted snow from the road like manual snow removal, but the material requirements of the shovel blade are very high. Through experiments, its hardness should be in the range of HRC52-58 and it should have certain impact resistance, and the appropriate snow removal speed is 5 km/h-30 km/h..
The snow removal speed of expressway or expressway is relatively high, and the net removal rate is relatively lower than that of urban roads. Therefore, the included angle between the shovel blade and the road surface is 75-80 (the acute angle formed), and the snow removal speed is15 km/h-60 km/h. Due to the harsh working environment of snow removal equipment, the whole equipment should be able to withstand various endurance in design, and the material selection should make the equipment have a certain degree after being stressed. The urban road snow shovel and highway snow shovel produced by Jilin Jieying are relatively successful designs, and the relevant structures can be referenced, but they cannot be copied because of intellectual property rights.
3. Snow removal roller brush is an indispensable equipment in snow removal machinery and equipment. The biggest advantage of roller brush is its high removal rate, but it is only limited to removing natural snow with relatively little snowfall. At present, due to the structural design defects of roller brushes, the pressure of roller brushes on the ground is not equal during operation, which leads to high or low speed or even parking, and the brush line is also worn or broken from the root, which is caused by uneven road surface and changes in tire pressure of installed vehicles. Therefore, the negative effects caused by these factors should be eliminated or compensated in the structural design of roller brushes.
There are sidewalks on both sides of urban roads, and there are many viaducts. Snow cleaned by roller brushes or other snow removal machinery should not be thrown at both sides, nor piled up at both sides, nor should it be repeated. Therefore, snow removal machinery and equipment should have the ability to directly throw the cleared snow to transport vehicles.
Research and Analysis of Multifunctional Vibrating Snow Shovel in Wang Xiushan
And the latest snow removal mechanical technology.
Wang Xishan
I focused on the research and development of snow removal equipment in 2000, and I was the inventor of "vibration" snow removal shovel. The research and design of snow removal machinery and equipment must first ensure the availability and performance of snow removal machinery and equipment. This paper analyzes the research of Wang Xiushan of Jilin University on multifunctional vibrating snow shovel, and briefly explains the structure that snow removal machinery and equipment must have in future design. I tried to make the language easy to understand, guided the thinking in the field of snow removal of research and development machinery and equipment, avoided misunderstanding and promoted the development of products.
Wang Xiushan of Jilin University's "Research on Multifunctional Vibrating Snow Shovel" (referred to as "paper") is based on the fact that Jilin University was entrusted by an enterprise in baishan city in the spring of 201/2000 to improve the production technology of vibrating snow shovel for the enterprise. This paper is far from the actual situation. The theory of "throwing effect", "vibration" and "obstacle height" mentioned in the abstract of the paper is far from the actual design theory and has great one-sidedness. Any mechanical equipment only has the latest design, not the best design. I am responsible for technology, products and society, which plays a correct guiding role in the research and development of deicing machinery and enriches the theoretical and practical basis in research and development.
At present, there is no mechanical equipment at home and abroad that can really clear the ice on the road area. One of the reasons is that snow removal machinery developed relatively late compared with other machinery, and there is no special requirement for countries to remove the ice formed on the road surface. The second reason is that the formation of ice is a typical material tri-state, that is, liquid water cools and forms a solid state on the road surface, so the affinity between ice and road surface is very strong, and the hardness of ice and asphalt is basically the same. It is difficult to peel off objects with the same hardness by mechanical force without damaging the road surface. I have made a breakthrough in effective deicing on the road surface, and the products will be available soon.
According to different national conditions, different countries in the world have different snow removal machinery and equipment, which have practical snow removal effects. As for the winter road snow in China, it has certain particularity, and the compacted snow accounts for more than 70%. Compacted snow has a very strong adhesion on the road surface and a certain affinity. At present, there is no mechanical equipment with stable performance to remove compacted snow at home and abroad. There are different protrusions on urban pavement and expressway pavement in China, which forces all kinds of snow removal machinery and equipment to have good avoidance. In this respect, all snow removal machinery is not ideal, even snow removal machinery with avoidance performance can not meet the requirements. All kinds of snow removal machinery and equipment developed and produced by Jilin Jieying have been verified by the market, and the removal effect of compacted snow, ice-snow mixture (snow is not completely frozen) and natural snow is very good. When you meet a protrusion on the road, you can pass by yourself, and the servo reset will continue to work after passing. On the one hand, it is worth learning and learning from the industry, and it is worth restructuring and expanding production to serve the society.
2. Analyze the concept of "Research on Multifunctional Vibrating Snow Shovel" by Wang Xiushan of Jilin University. The theory of "throwing effect", "vibration" and "obstacle height" mentioned in this paper is far from the actual design concept and has great one-sidedness.
1, "vibration" dialysis machinery and equipment have vibration performance, which does have certain effects, but it is by no means "vibration". Vibration and "vibration" are not the same concept. The shovel to clear the compacted snow mainly lies in the design of the included angle between the shovel blade and the road surface and the design of the obstacle-crossing structure. Vibration refers to the overall active vibration of mechanical equipment, and shovel blade is the executive structure of snow shovel. The shovel blade has the function of vibrating more than 5000 times/minute, and forms a certain angle with the road surface, which can play a very good role in removing ice and snow (I have completed this vibrating shovel after years of research and development, and it will be available soon, and this vibrating shovel can remove ice and snow). "Vibration" refers to a form of active reciprocating motion of mechanical equipment. "Vibration" should have certain restrictions on all kinds of mechanical equipment, and the frequency of "vibration" should not be too high, otherwise the mechanical equipment will produce * * * vibration, which will make the equipment unable to work. In the snow removal machinery and equipment, if the included angle between the shovel blade and the road surface is suitable for snow removal, the structural mass of the "vibrating" connector is 300kg, the "vibrating" reciprocating is 8mm, and the frequency is 600 times /min. The whole snow removal machinery does not produce * * * vibration. According to this set of data, the linear speed of the shovel blade is 4800mm/min. If the working speed of the whole snow removal machinery and equipment is set to 50000 mm/min(3km/h), the shovel blade will not vibrate back and forth, that is, the vibration will not reach the performance of "ice and snow breaking" in snow removal operation. Therefore, the experiment of breaking ice and removing snow with vibrating shovel mentioned in the abstract shows that the cleaning rate of vibrating shovel can reach 95% for different ice and snow densities, which meets the requirements of modern snow removal.
2. The "obstacle-crossing test" describes that the performance of unilateral snow removal operation is very important, which determines whether the snow removal shovel can carry out snow removal operation. Jilin University copied the snow shovel structure produced by Jilin Baishan Enterprise and applied for a utility model patent (20 122027 1647.4) (Wang Xiushan was one of the participants). The main structure described and the national patent (20 1020162655) applied by others as early as 2010. With the continuous wear and tear of the shovel blade in the operation, its obstacle-crossing height also changes, and the obstacle-crossing phenomenon is bound to appear at any time in the snow removal operation. Therefore, it is very one-sided to explain that "the maximum height that the snow shovel can cross obstacles is 140mm through the obstacle-crossing test". There are many kinds of mechanical structures that can make the shovel edge achieve obstacle-crossing effect. I have designed a variety of snow shovels that can roll over obstacles, reset obstacles automatically, compact without vibration or vibration, and quickly remove snow on roads, which will soon face the market.
3. This paper discusses that the dialysis snow shovel will slide to one side with the included angle between the radian of the main board of the snow shovel and the working direction after peeling off the road. The speed and height of sliding discharging are directly related to the material of the shovel blade, the included angle between the shovel blade and the ground, the included angle in the walking direction, the radian of the main board, the viscosity of snow, the size and density of snow particles (blocks), the speed of operation, the weather temperature and so on. This kind of machinery is a non-standard mechanical design with the ultimate goal of operation purpose, operation effect and operation cost. Therefore, this article
The "good throwing effect of snow shovel" in the paper is very one-sided. The throwing effect should be determined by sidewalks, buildings, etc. Not affected, and don't throw snow on both sides of the viaduct or pile it up in the city.
Three. Basic requirements for structural design of snow removal machinery and equipment
1, the present situation of snow removal machinery in China, the cities that snow in winter are basically snowing while vehicles are driving on the road, so the roads in cities are mainly compacted snow. At present, there is no mechanical equipment with stable performance except the vibration-free snow shovel produced by Jilin Jieying. Due to the unreasonable design of the included angle between the shovel blade and the road surface and the insufficient design of obstacle crossing, all kinds of snow shovels are basically limited by downward pressure during operation, which makes the snow shovels unable to achieve snow removal performance. Due to the fast consumption of wearing parts and insufficient structural design, the whole snow removal mobile machinery is unstable. Because the market demand of snow removal machinery is large, there is a certain profit space, and it can be realized by general manufacturing methods, which urges units or individuals with certain conditions to produce and sell with one idea, which makes the market of snow removal machinery and equipment chaotic.
2. Basic requirements of snow removal machinery and equipment in structural design. The design of obstacle-crossing structure and the angle between shovel blade and road surface directly affect the performance of snow removal machinery. According to many years' experiments and research on various kinds of snow, the snow shovel is the best choice for snow removal on urban roads. The included angle between the shovel blade and the road surface is 30-50 according to different road conditions and snow conditions, and the shovel blade is the best design after crossing obstacles. The hardness of compacted snow is very different from that of general hardened pavement. According to the mechanical analysis of manual snow removal with shovel, the shovel blade must have three points of force, so that the shovel blade can peel the compacted snow from the road like manual snow removal, but the material requirements of the shovel blade are very high. Through experiments, its hardness should be in the range of HRC52-58 and it should have certain impact resistance, and the appropriate snow removal speed is 5 km/h-30 km/h..
The snow removal speed of expressway or expressway is relatively high, and the net removal rate is relatively lower than that of urban roads, so the included angle between the shovel blade and the road surface is 75-80 (the acute angle formed), the snow removal speed is 15 km/h-60 km/h, and the working environment of snow removal equipment is relatively harsh. In design, the whole equipment should be able to withstand various endurance, and the selection of materials should make the equipment have certain elastic deformation after being stressed. The urban road snow shovel and highway snow shovel produced by Jilin Jieying are relatively successful designs, and the relevant structures can be referenced, but they cannot be copied because of intellectual property rights.
3. Snow removal roller brush is an indispensable equipment in snow removal machinery and equipment. The biggest advantage of roller brush is its high removal rate, but it is only limited to removing natural snow with relatively little snowfall. At present, due to the structural design defects of roller brushes, the pressure of roller brushes on the ground is not equal during operation, which leads to high or low speed or even parking, and the brush line is also worn or broken from the root, which is caused by uneven road surface and changes in tire pressure of installed vehicles. Therefore, the negative effects caused by these factors should be eliminated or compensated in the structural design of roller brushes.
There are sidewalks on both sides of urban roads, and there are many viaducts. Snow cleaned by roller brushes or other snow removal machinery should not be thrown at both sides, nor piled up at both sides, nor should it be repeated. Therefore, snow removal machinery and equipment should have the ability to directly throw the cleared snow to transport vehicles.
Four. The application of my newly designed snow removal machinery and equipment makes snow removal in winter fast. However, due to the harsh use environment of snow removal equipment and the lack of good business and technical training for users, products in this field should have good performance and stable performance. The research and development of snow removal machinery and equipment is a very complicated and difficult technical project. After years of research and production tests, various road snow removal machines have been successfully developed and come out, which have been well received by the market. The appearance of these products and technologies marks a new development period and a qualitative leap in the field of road snow removal machinery in China, and also marks that China is ahead of the international level in the field of snow removal machinery and road cleaning equipment.
According to the diversified road construction mode and snow situation in China, all kinds of brand-new snow removal machinery and equipment have been designed and developed. These series of snow removal machinery and equipment can remove snow from various roads, compact snow, reduce snow removal procedures, reduce snow removal cost per unit area, save snow removal cost and reduce the labor intensity of operators.

Verb (abbreviation of verb) road cleaning vehicle
1. The brushless and pollution-free sweeper is newly designed. Brushless and pollution-free summer road sweeper adopts a unique high-end structural design, so that road pollutants can be removed with the flow of air. Due to the structural innovation, the heavy objects on the road surface can be easily collected into the garbage storage box. Because the road surface cleaning does not need to be brushed, it reduces a lot of costs for the sanitation department and saves a lot of money for the country.
2. Roller brush pollution-free universal sweeper This roller brush is a newly designed universal sweeper that is pollution-free all year round. It adopts a unique high-end structural design in design, which can remove all kinds of pollutants and snow on the road at one time. Due to the structural innovation, it is easy to collect heavy objects and snow on the road to the storage bin or both sides of the road, which realizes multi-purpose of one machine, reduces the cost for the sanitation department and saves a lot of money for the country.
3. Road surface cleaning vehicle for recycling sewage At present, the road surface cleaning vehicle cannot actually recycle sewage when cleaning the road surface, and pollutants on the road surface still exist on the road surface. According to the principle of fluid mechanics, the road cleaning vehicle produced by this technology recovers the sewage from road cleaning into the sewage pool, so that the pollutants polluting the road surface can be completely removed from the road surface, and the purpose of truly cleaning the road surface can be achieved.
The technology of sanitation machinery is a vast technical field, and I would like to discuss the technical exchange in this field in order to improve the technical level and manufacture products with low price, stable performance and meeting the market demand.
