Simulation and Distortion Analysis of Hydro-pneumatic Suspensions
摘要
Abstract
To improve the performance of hydro-pneumatic suspensions(HPS), a coupled HPS with variable parameters is designed. Its working principles and structure characteristics are analyzed. The mathematical model of distortion which appears in HPS cylinder under high speed excitation is deduced, and the key parameter curves during the distortion are obtained by simulation. The Simulink simulation model is established according to the nonlinear mathematical model. Simulation analysis and bench test are carried out using selected parameters. The simulation results show that the HPS has good nonlinear characteristics, and the distortion appears under the excitation of high frequency and amplitude. The simulation results are in good agreement with the experimental results, which shows that the established mathematical model has high accuracy and can be used to study the HPS.关键词
