1 Purpose and characteristics

  The test system is flexible to use. It can perform coordinated loading tests between four channels and single-channel loading tests. Users can configure test fixtures according to test needs to perform loading tests on body, suspension and various other components.

2 Program description: The test system is mainly composed of four servo linear actuators 20KN, four-channel hydraulic oil separation filter oil storage module, four-channel all-digital servo controller, related test software, other necessary loading brackets and accessories, etc. .

3 Main technical performance indicators:

3.1 Maximum static test force: ±20kN, calibrated according to 1, 10 attenuation multiples, and the display accuracy is ±1% from 20% for each file

3.2 Maximum dynamic test force: ±20kN, the amplitude fluctuation is not more than ±2%FS for each gear. 

3.3 The maximum amplitude of the actuator: ±100mm (negotiable), with an indication accuracy of ±0.5% FS from 20%. 

3.4 Frequency range: 0.01-40Hz (negotiable). 

3.5 Main test waveforms: sine wave, square wave, triangle wave, ramp wave and user-defined wave. 

3.6 Configure 220L/min constant pressure servo pump station
