Fatigue test-bed for automobile suspension system

...
产品用途

The fatigue test-bed of automobile suspension system completes the quasi-static and quasi-dynamic tests of vehicle and suspension system under multi-road conditions, vehicle modal test, vehicle ride comfort test and NVH performance research, and studies and evaluates the characteristics of key components such as automobile suspension system and seat system.

It can meet all kinds of loading signals of real-time road conditions, and it can be fully driven under laboratory conditions. It can accurately simulate the road spectrum function through iterative algorithm, and complete complex actual road simulation tests under laboratory conditions.

FRF transform and calculation with multi-channel excitation, definable PSD signal, automatic iteration and frequency sweep; Number of channels: four channels and six channels; Parameters are determined according to customization requirements.
