摘要
按汽车行驶平顺性评价方法,应用MATLAB工具箱编制了针对五自由度汽车模型的随机输入动态仿真程序。通过仿真可直接获得给定测点的加权加速度均方根值分量的最大值和总加权加速度均方根值。仿真结果与随机输入行驶试验结果基本吻合,证明仿真方法是正确的。该程序可用于汽车悬架系统参数的设计和平顺性的评估。
According to appraisal method of automotive ride comfort, a random input dynamic simulation program for five DOF's vehicle model is developed, using Matlab toolbox. Through simulation, the maximum root mean square value of weighted acceleration and the root mean square value of total weighted acceleration of given points are obtained directly. The simulation results coincide well with that of random input running test. So the method is proved to be correct, which can be applied to the design of vehicle suspension system parameter and the assessment of vehicle ride comfort.
