微型客车整车多体系统动力学的建模与仿真

Modeling and Simulation of a Mini-bus With Dynamics of Multi-body Systems

国内某微型客车采用了若干体现当今微型车发展方向的结构特征。在ADAMS软件系统基础上,建立了该车整车多体系统动力学的仿真模型,验证了应用该模型模拟仿真整车操纵稳定性的准确性;通过方向盘转角阶跃输入、蛇行转向、直线制动和复杂道路等典型行驶工况性能仿真分析,从多个方面对整车的操纵稳定性进行了分析和评估。

A few of new structures, which represent technical characteristics of mini- bus design today, have been applied into development of a new type mini- bus. Modeling of the mini- bus with dynamics of multi- body systems was researched into by using the ADAMS software, and then validity of the vehicle model was verified. Furthermore the operational stability of the mini- bus was investigated and evaluated by simulation analyses such as step steer analyses, snake cornering analyses, braking analyses in line, as well as complicated course analyses and so on.
