具有独特悬架系统的旅行车操纵稳定性仿真

A Simulation Model for Controllability and Stability of the Wagon with Unique Suspension System

利用ADAMS/car软件建立能全面反映旅行车动力学特性的整车操纵稳定性模型,并开发了汽车操纵稳定性计算机分析评价系统.根据操纵稳定性的试验方法和评价指标,对某型旅行车的稳态回转试验等项目进行仿真计算,同时进行了整车操纵稳定性试验.结果表明:该型旅行车的稳态回转特性评价为不合格.所建立的整车操纵稳定性模型和开发汽车操纵稳定性计算机分析评价系统是可靠的,能用于汽车操纵稳定性的优化设计.

A multi-body system dynamics simulation model was established for a wagon by means of a redeveloped module of ADAMS/CAR. According to the national standard and the test evaluation method on the vehicle steering stability, the simulation and tests under typical working conditions were performed and discussed. The results indicate that the simulation is precise and reliable. The multi-body system dynamics simulation model can be applied to the optimization of Controllability and Stability.
