Abstract

The invention relates to a multifunctional automobile shock absorber and a quarter suspension simulation working condition test bench. Including mechanical bench part, hydraulic vibration part and computer control system part. The invention has multiple functions, and can realize the simulated working conditions of ordinary cylinder oil pressure shock absorbers, magneto-rheological fluid shock absorbers, ordinary passive quarter suspensions and magnetorheological semi-active quarter suspensions test. According to the test results, the performance of a single shock absorber and the overall performance of the suspension can be analyzed, and the control effect of the magnetorheological semi-active suspension under different control strategies can be verified.

Description

technical field [0001] The invention relates to a test bench for a multifunctional vehicle shock absorber and a quarter suspension simulation working condition. Background technique [0002] With the development of my country's automobile industry, the requirements for the 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 they have single functions and simple test conditions, which cannot meet the requirements of simulating real working conditions. In particular, the suspension test bench is mostly used for real vehicle testing, and it is difficult to obtain the application effect of different shock absorbers in the same suspension system, and the key component of the suspension system is the shoc...
