test condition
1. 1 Double magnetic circuit structure: Compared with the single magnetic circuit, the magnetic field intensity is stronger, the mesa volume is smaller, and the magnetic leakage is less than or equal to 5 mt, which is convenient for testing the magnetic-repellent samples.
1.2 moving coil skeleton of vibration table: exquisite material selection and high specific stiffness make the moving coil system light in weight, high in no-load acceleration and high in first-order natural frequency of the moving coil, thus making the waveform distortion in the working frequency band small.
1.3 suspension device: the double fulcrum guidance of torsion spring-rolling arm and linear bearing ensures the good guiding performance of the vibration table, and has high anti-eccentric load ability, so that the lateral vibration of the table is small.
1.4 trunnion vibration isolation: vibration isolation frequency
1.5 air spring support: strong bearing capacity, good low-frequency performance and strong creep resistance.
1.6 reasonable cooling design: forced air cooling of large-tonnage thrust vibration table is realized, with low cost, high reliability and convenient maintenance.
The optimal impedance matching between 1.7 platform and power amplifier ensures the low power consumption, low temperature rise and high reliability of the system.
1.8 has complete protection functions: it has protection functions such as output overvoltage, output overcurrent, over-displacement, overload, simulated over-temperature of power amplifier, zero signal start and so on.
1.9 has strong matching performance: it can complete sinusoidal, random and classical impact tests when matched with random vibration control system.
