| 摘 要： | 对影响汽车行驶安全的各方面因素进行了较为深入的分析和研究,建立车体6个自由度加上前轮转向系统1个自由度的汽车数学模型;该汽车数学模型不需引入很多的人为假设;可以实现给定汽车前轮转角,也可以不给定前轮转角;不依赖需要复杂测定的侧向力函数及相关模型参数;考虑了轮胎的滚动特性。利用MATLAB语言开发了一个模块化的仿真软件,该软件能够满足所建模型的校验和在特殊工况下的仿真研究;也可以进一步完善该软件使之服务于汽车运行的其他方面的仿真研究。

| Abstract: | The essay focuses on in-depth analysis and study on various elements which influence driving safety of cars by establishing a controllable simulation mathematical model of car operation.The car body has six degrees of freedom,plus a typical car front wheel steering system model.In the car simulation model there's no need to introduce many man-made hypothesis to realize a given car front wheel steering angle or without given one,without depending on lateral force function or related model parameters in need of(complicated) measurement;and with consideration of the rolling characteristic of tires.A modularized simulation software is developed by MATLAB language,which meets the needs of test and the simulation for particular situation,and it also can be developed further for other simulation study of car operation. |
