基于ADAMS和MATLAB的车辆半主动悬架系统的研究

Research of Vehicle Semi-active Suspension System Based on ADAMS and MATLAB

基于Adams建立了整车多体系统动力学仿真模型,基于VB编写了国家B级路面生成程序,并将模型和程序导入Matlab,在Matlab/Simulink环境下建立模糊控制系统,进行基于Adams与Matlab的联合仿真,实现虚拟环境下车辆行驶平顺性的仿真研究。研究结果表明,模糊控制的半主动悬架系统明显减少了车辆振动,因此,有效地改进了车辆的行驶平顺性和乘坐舒适性。

Multi-rigid-body dynamics simulation model of vehicle was established by Adams,and generating program of national B-road was compiled by VB software. Then the model and program were imported to Matlab. In Matlab/simulink, fuzzy control system was established. By the co-simulation based on Adams and Matlab, the research of ＂vehicle ride performance in virtual environment was realized. The simulation result shows that fuzzy control semi-active suspension can reduce the vibration of the vehicle and improve its ride comfort.
