基于键图理论对安装EPS系统的车辆操纵稳定性的仿真分析

Analysis and Simulation of Handling and Stability of Vehicles with EPS Based on the Bond Graph Theory

应用键图理论建立电动助力转向系统(EPS)的模型,将电动助力转向系统的键图模型和matlab的simulink仿真方框图相连接,并利用simulink的可视化功能实现汽车操纵稳定性的可视化仿真,仿真结果表明,将simulink仿真工具箱与键图模型相结合,可使汽车性能分析研究更为直观和简洁。

Establishing a model of the electric power steering by the bond graph theory, connecting the model of the EPS with the matlab/simulink simulation toolbox and using the visible function of the simulink can realize visible simulation of handling and stability of vehicles. The simulation result shows that connecting simulink simulation toolbox with the bond graph model can make automobile capability analysis more clear and simple.
