Flow

160L/min, three oil filtration system

Operating software

based on the staffing management program on 

the windows platform and shock absorber test 

application software, with convenient smart, 

simple and practical functionality  

With displacement and load of two control modes can smoothly switch during the test. 

Function generator with sine wave, triangle wave, square wave, 

inclined wave, superposition of wave, and can be input.

Features:

♦ A variety of control compensation function (including peak value compensation, amplitude phase 

compensation, the dynamic response of the inverse adaptive compensation, etc.), the user is almost 

no need to adjust the P, I, D parameters, can automatically compensate for sample stiffness. 

 Advanced all-digital signal processing technology, the system resolution of 19. The sensor calibration 

adopt 19:00 linearity correction. The sensor signal with a variety of filters to provide a high-precision, 

low-drift, low-noise performance, and further guarantee the accuracy of the measurement results.

 Users can be custom programmed combination of test and control mode after the pre-set automatic

switching control mode during the test. 

 Function generator waveform variety, in addition to the conventional waveform can also accept 

external input waveform and spectrum file specifies the format of the reproduced waveform.

 System sampling frequency up to 6kHz. Provide analog and digital input and output interfaces, data 

acquisition and graphical display function, complete limit and failure protection function. 

 Compensation coordination between channels and independent control functions. The control system

 can control the the main actuators and lateral force load actuator, coordinated loading function.

 With optional software features. According to the actual need to select the software. Dedicated damper

 test software is simple, a wide range of test types.
