Common shock absorber test bench
According to the vibrator composed of motor, rack, flywheel of energy storage pump elastic yellow, it drives the cabinet table the shock absorption equipment of the tested vehicle to cause vibration. After a few seconds of start-up, the switching power supply of the motor is cut off, the flywheel of the energy storage pump causes sweep frequency excitation. Because the frequency of the motor is higher than the resonance frequency of the wheel, the whole process of sweep frequency excitation of the flywheel of the energy storage pump can sweep the bearing of 408 shock absorber to the original vibration frequency of the wheel wheel, then cause the common vibration of the cabinet table automobile system. According to the vibration curve of force offset in the whole process of testing the vibration attenuation coefficient after excitation, the characteristics of frequency attenuation coefficient can be obtained, the working characteristics of shock absorber of shock absorber can be distinguished.
Common shock absorber test bench
1-flywheel of energy storage pump; 2-motor; 3-rack; 4-excited elastic yellow; 5-cabinet table, precision measuring equipment, force measuring shock absorber test bench offset shock absorber testing bench; one is the force in the whole process of measuring vibration attenuation coefficient, the other is the offset in the whole process of measuring vibration attenuation coefficient. Their structure is shown in Fig. 16-15. Because of the stable performance of the test bench of the shock absorber reliable data information of the shock absorber bearing chip, it is widely used.
