基于ADAM S软件的多功能车操纵稳定性仿真研究

Simulation research on multi-purpose vehicle handling stability based on ADAMS

汽车的操纵稳定性不仅影响到汽车驾驶的操纵方便程度,而且是决定高速汽车安全行驶的一个主要性能。文章利用ADAMS软件建立了某多功能车(MPV)的整车多体动力学模型,在不同的环境模式下对表征车辆操纵稳定性能的时域响应与频率响应特性进行了大量的计算和仿真,为改进、优化产品提供了重要的参考数据。

The handling stability of automobiles not only influences the convenient degree of handling but also is a main performance index for characterizing the safe high-speed running of automobiles. In this paper, a multi-body dynamic model of a certain multi-purpose vehicle（MPV） is established by using the ADAMS software, The tests which reflect the time domain response and the frequency domain response are simulated and calculated,and the obtained results are verified by practical experiments. The study results offer important reference data for improving and optimizing the products.
