摘要
本文论述了以多刚体系统动力学理论为基础,在ADAMS下建立汽车49自由度虚拟样机模型,并进行了系统动力学仿真。相比传统的基于集中质量较少自由度的抽象模型,它对汽车的动力学描述更为全面、准确,是今后汽车虚拟设计及分析的必然发展趋势。
In this paper, based on the theory of multi -rigid - body system dynamics , a virtual prototype of one passenger car with 49 degrees of freedom is developed under ADAMS. Then a variety of typical vehicle dynamics simulations is carried out. Compared with traditional car models,this virtual prototype brings about more detailed and accurate results on vehicle perfomance.
