Abstract

The invention discloses a multifunctional test bed for simulating condition by a one-quarter suspension of a vehicle, comprising a T-shaped groove base, a test bed support frame, an actuating bench assembly and a vehicle suspension assembly. The test bed support frame is arranged on one side of the T-shaped groove base; and the actuating bench assembly is arranged on the other side of the T-shaped groove base. The vehicle suspension assembly is arranged on a working disk of the actuating bench assembly; and the vibration response of a vehicle body and unsprung mass can be obtained by simulating the road surface vibration through the output of an actuating bench. The multifunctional test bed has multiple functions, can meet simulation condition tests of transverse arm type, multi-link type and Macphersan type suspension systems in the suspension forms, meet simulation condition tests of passive, semi-active and active suspension systems in the types and meet actual condition tests and pseudo-dynamic tests in the simulation modes. According to the test results, the invention not only can analyze the performance of single vibration absorber, but also can analyze the overall performance of the suspension and can verify control effects of magnetorheological semi-active suspension under different control strategies.

Description

technical field [0001] The invention relates to a multifunctional test stand, in particular to a multifunctional test stand for a vehicle quarter suspension simulation working condition. Background technique [0002] With the development of my country's automobile industry, the performance requirements of the vehicle suspension system and its key components - shock absorbers are getting higher and higher. The way to evaluate the performance of the two is to obtain performance parameters through experiments and judge according to certain standards. At present, test benches for shock absorbers and suspensions have been used in the industry, but shock absorber test benches often refer to shock absorber dynamometers and shock absorber fatigue test benches. The test items are single and cannot meet the requirements of simulation. The requirements of real working conditions. However, some suspension test benches often ignore the effect of the suspension rod system, and only cons...
