以某型轿车底盘为研究对象，采用虚拟样机软件ADAMS建立整车多体动力学仿真模型；结合汽车操纵稳定性的客观定量评价标准，建立了直接生成操纵稳定性评价值的ADAMS函数；用ADAMS软件结合正交试验方法对整车操纵稳定性进行了虚拟正交优化设计。虚拟样机技术在车辆操纵稳定性参数正交优化中的应用，不仅使仿真模型与集中质量模型相比提高了精度，还分析出整车操纵稳定性的主要零部件影响因素，得到了最优的一组设计方案。由于是直接对具体零部件的优化，整个设计过程适于在企业中应用。

Based on the chassis of a car, a multi-body dynamics model was built with ADAMS software. With the objective evaluation index for maneuverability of vehicle, ADAMS function was built to evaluate vehicle maneuverability. Orthogonal optimization design was applied to optimizing vehicle maneuverability with ADAMS software. The applying virtual prototyping technology for vehicle maneuverability and structure orthogonal optimization not only increases accuracy of simulation model compared with lumped-mass model, but also finds the main factors influencing the vehicle maneuverability and gets the optimization levels of the influence factors. The design process can be used in industrial organization.
