基于多刚体动力学技术的某MPV稳态转向特性分析

Analysis of some MPV steady state steering characteristic based on.dynamic of multibody technique

为了研究和改善某MPV整车稳态转向特性，在Adams／Car平台中建立了整车动力学模型，并根据实际测量获得的悬架和整车性能试验数据进行对比验证。在此基础上，根据稳态转向特性的评价指标对此MPV稳态转向特性进行优化，提高车辆的操纵稳定性。

In order to research and improve the steady state steering characteristic of some MPV,establishes complete vehicle dynamic model in Adams/Car platform,and verified by comparasion of experiment data suspension and complete vehicle performance through actual measurement.On that basis,makes optimization of MPV steady state steering characteristic according to steady state steering characteristic,improves the operation stability of vehicle.
