Academician Zhao is over 80 years old, still? Stick to fitness and engage in scientific research? Zhao Chunsheng, an academician of China Academy of Sciences and an expert in mechanical engineering, had a crack in his eye during an interview? I am very excited and glad that I still insist on fitness and scientific research technology. You can't buy or get it, you can only create it yourself. ? Among them, Zhao Chunsheng, an academician of China Academy of Sciences and a professor at Nanjing University of Aeronautics and Astronautics, is the first scientist to study electric vibration exciter in China, and also the founder and pioneer in the field of ultrasonic motors in China. Under his leadership, the team developed more than 60 kinds of ultrasonic motors and drivers with independent intellectual property rights, which made important contributions to Air China and national defense. ?
Ultrasonic motor uses the inverse piezoelectric effect of piezoelectric ceramics and ultrasonic vibration to obtain motion and torque, and through mechanical vibration amplification and friction coupling, the tiny deformation of materials is transformed into the rotary (or linear) motion of the rotor (or rotor). In this new type of motor, the piezoelectric ceramic disk replaces many copper coils in the traditional motor.
Zhao Chunsheng? Old job? It's not an ultrasonic motor, but vibration engineering and its application. As early as 1960s, Zhao Chunsheng in his 80s saw what China used. Electric exciter? When they were imported from abroad, they plunged into it? Vibration exciter? In the process of development, we finally made our own efforts to create China people's own? Vibration exciter? It fills the domestic blank and is the founder and pioneer in the field of ultrasonic motors in China.
