基于键合图的整车转向振动仿真

Simulation on the Vibration of Complete Vehicle Turning Based on Bond Graph

基于键合图理论建立了某车整车转向模型,采用滤波白噪声作为路面输入,进行了侧向加速度为6.67m/s2时的转向仿真,通过对车身垂直加速度、俯仰角和侧倾角仿真结果的分析,对原车悬架系统进行了优化.

A vehicle steering model was established with the bond graph theory.Using the filtered white noise as road input,a steering simulation is proceeding when the lateral acceleration is 6.67m/s2.The original suspension system is optimized with the analysis results of the vertical acceleration,pitch angle and roll angle of the vehicle body.
