摘要

本文提出了一种基于AMESim和MATLAB/ Simulink的仿真建模方法。目的是通过集成控制车辆底盘系统来提高车辆的乘坐舒适性和操控稳定性。在此基础上,建立了汽车半主动悬架与电动助力转向的联合仿真模型。应用AMESim软件建立了SAS和EPS的力学动力学模型。利用MATLAB/Simulink建立了汽车底盘系统的综合控制器模型。通过建立s函数连接AMESim和Simulink的接口。联合仿真结果表明,在综合控制的情况下,操纵稳定性和平顺性优于单独的SAS控制或单独的EPS控制。验证了该仿真模型的有效性,为研究汽车底盘动力学仿真提供了一种新的方法。

Application of AMESim & MATLAB simulation on vehicle chassis system dynamics
This paper presents a simulation modeling way which used by software AMESim and MATLAB/ Simulink. The aim is to improve vehicle ride comfort and handling stability through integrated control vehicle chassis system. Then co-simulation model for vehicle semi-active suspension (SAS) and electric power steering (EPS) is present. AMESim is applied to build mechanical dynamics model for SAS and EPS. MATLAB/Simulink is used to build the integrated controller model of vehicle chassis system. Through build s-function to connect interface of AMESim and Simulink. Co-simulation results prove that in the case of integrated control, handling stability and ride comfort is better than solo SAS control or solo EPS control. In a word, the simulation model is proved to be valid, and it is helpful to provide a new method to research vehicle chassis dynamics simulation.
