Abstract

The invention discloses a vehicle quarter simulated suspension system and a damper characteristic composite test bench, consisting of two parts of a whole frame-based suspension system test bench and a damper characteristic test bench which are comprised relatively a mechanical bench part, an electric excitation part and a computer control part. The invention is capable of performing characteristic test, ordinary passive and semi-active quarter suspension characteristic test of various dampers, and development test of semi-active suspension controller. Using frame structure and vertical straight ball slide, and with simple and stable bench structure, little mechanical friction and convenience for adjusting suspension parameter, it is capable of using various suspension parameter in computer simulating calculation in the test, which enables good connection between numerical simulation and test validation, thereby improving the effect of the suspension performance test and semi-active suspension controller development test.

Description

Technical field: [0001] The invention relates to a comprehensive test bed for a quarter simulated suspension system and shock absorber characteristics of an automobile. Background technique: [0002] The automobile suspension system is responsible for supporting the car body, ensuring the important task of driving smoothness and driving safety. In order to improve the performance of the suspension system, people often adopt the method of optimizing various suspension parameters, but this optimization has a certain limit. In recent years, attempts have been made to use semi-active suspensions to further improve the damping performance. The easiest way is to make the damping of the shock absorber adjustable. The shock absorbers with adjustable damping include magneto-rheological, electro-rheological, and hydraulic damping. And so on. Due to its excellent characteristics, semi-active suspension is an emerging technology that is most likely to be promoted and applied in the ma...
