Product information
The test machine adopts electro-hydraulic servo control technology, which is suitable for all kinds of cylinder vibration absorber's static and dynamic performance test (indicator test, speed characteristic test), fatigue life test (durability test), temperature characteristic test and so on. The test method meets the relevant requirements of the standard for automobile cylinder shock absorber test (QC/T545-1999) and the technical conditions and test methods of motorcycle and moped shock absorber (QC/T62-2007).
Functional characteristics
A variety of control and compensation functions, including peak valley compensation, amplitude phase compensation, dynamic response adaptive compensation, etc., users can hardly adjust the parameters of P, I and D automatically, and can automatically compensate for the sample stiffness.
Advanced full digital signal processing technology, the system resolution is 19. 19 point linear correction is used for sensor calibration. The sensor signals have a variety of filters, which provide high precision, low drift and low noise performance, and further ensure the accuracy of the measurement results.
The user - defined program control combination test can be carried out, and the control mode is automatically switched in the process of pre - set test.
The function generator has many kinds of waveforms, besides the conventional waveform, it can also accept the external input wave and the reproduced waveform of the specified format.
The sampling frequency of the system is as high as 6kHz. Provide analog and digital input and output interface, rich data collection and graphic display function, complete limit and failure protection function.
