非线性空气悬架的动力学特性研究

Study on dynamic characteristics of nonlinear airsuspension

为研究空气悬架的动力学特性,综合考虑空气悬架系统机械、气动、控制等部件间的相互作用,基于AMEsim仿真平台建立空气悬架的一维动力学模型,对特定工况下的空气悬架进行动力学仿真研究。仿真结果表明,空气悬架可以有效降低激励导致的系统振动频率,提高行车品质。

For studying dynamic characteristics of airsuspension, considering complexly the interacting among mechanic, air-actuated, controlled parts of airsuspension system, it proposes a dynamic model in linear dimension about airsuspension based on emulator flatform of software AMEsim, and makes a dynamic simulation study on airsuspension in special work condition. Simulation results indicate： air suspension can reduce effectively the vibration frequency of system caused by motivation, and improve the travelling trait.
