Research on Synchronous Testing Technique of the Shock Absorber Performance in Automotive Coaxial Suspension

Abstract:

According to the test specifications of Bench test methods of automotive telescopic shock absorber（QC/T545-1999）, through controlling variable frequency motor which drives crank-link-slider mechanism，harmonic excitation is acted on shock absorbers. Meanwhile, signals of two force sensors and displacement sensor are acquired. The synchronous performance test of single condition and multi-work condition is achieved for shock absorbers in automotive coaxial suspension. The velocity characteristic and resistance-displacement characteristic are tested in specified range of the velocity of motor.
