Testing and manufacture to shock absorber electro-hydraulic servo-testing system

摘要

The shock absorber Electro-hydraulic Servo-testing system conformed to national standard QC/T 545-1999 is designed, error compensating PID regulation method which is appropriate for signal condition was applied. According to use the MTS407 controller and LabVIEW virtual instrument software, implement dynamometer diagram testing, speed diagram testing, friction diagram testing, temperature wearing diagram testing, wearing life testing, single and double actuator testing and whole frequency testing are implemented. After the experiment conducted by using shock absorber CA1049, the result shows that the testing system can collect large volume of data, and is high precision. The characteristic curve obtained by the testing system was smooth and comformity with the China standard completely.
