Analysis on Sensitivity and Influencing Factors of Force-displacement Characteristics of Dual-cylinder Hydraulic Shock Absorbers
摘要
Abstract
The working principle and structure characteristics of dual-cylinder hydraulic shock absorbers are analyzed. A one dimensional (1D) simulation model for the absorbers is built by using the software AMEsim. The structural parameters of a domestic hydraulic shock absorber are employed for the simulation of the model under different working conditions. Results of the simulation are verified by the performance test of the absorber. It is shown that the 1D model of the hydraulic shock absorber based on AMESim software can well simulate the real working condition of the hydraulic absorbers. This model can be used to analyze the sensitivity of 25 conventional design parameters, including the stiffness of the throttle valve tongue, throttle orifice area, inflation pressure etc., to the force-displacement characteristics of the shock absorbers and the variation tendency of the 25 parameters under some typical working conditions. This study may provide an effective basis for research and development of common dual cylinder hydraulic shock absorbers.关键词
