公路行车动力学仿真分析的研究

Study on the Highway Dynamics Simulation Analysis

研究了公路上行驶车辆的乘车舒适性问题,为公路线形设计阶段提供了一种质量检查的参考手段。结合海口市羊山路网一期工程项目(主干道北段)道路工程实例,利用纬地软件和新型商业UM软件(Universal Mechanism),建立道路的平竖组合线形和车辆的左右轮超高模型来进行汽车动力学仿真分析。另外,在仿真计算时,还考虑了公路的不平顺,与实际公路更为接近,减小了误差。

Study on the ride comfort issues of the road vehicle, which provides a reference means of quality inspection of the road during the design stage. With first phase project of Yangshan（ the main road North） road height of the vehicle left and right wheels for vehicle dynamics simulation analysis. During the simulation calcu- lations, the irregularity of the roads is also taken into account to reduces errors.
