摘　　要：在众多的交通事故诱发因素中,道路条件与限速要求是一个不容忽视的重要因素。使用SolidWorks进行汽车运动仿真,分析了弯道倾角、弯道半径、转弯速度的变化对汽车转弯侧滑及侧翻安全性的影响,为科学合理地制定斜面弯道的车辆限速值提供了理论依据,对减少平曲线路段交通事故的发生具有重要意义。In many traffic accident-causing factors,road conditions and speed limit requirements are important factors that cannot be ignored.In this paper,SolidWorks was used to simulate the vehicle motion,and the influences of changes in the angles of curve,radius of curves,and turning speed on the safety of turning and side rollback of the vehicle were analyzed,which provides a theoretical basis for scientifically and rationally setting the vehicle speed limit value of the curve.It is of great significance to reduce the occurrence of traffic accidents on the flat curve road sections.

关 键 词：弯道半径 弯道倾角 汽车限速
