摘　　要：汽车列车是牵引汽车与挂车相互作用、相互耦合的复杂系统,其横向稳定性研究涉及多体动力学、刚柔耦合力学、气体动力学、车辆非线性运动和电子控制等多个学科。本文论述了汽车列车横向稳定性的国内外研究现状、研究方法和试验手段,探讨了使用参数和结构参数对汽车列车横向稳定性的影响,分析了角阶跃输入下汽车列车侧向加速度响应。最后,对汽车列车动力学数字仿真算法及代表性软件进行了分析阐述。The road train is a complex system with interaction and coupling between the tractor and trailer. The study on lateral stability is mttltidisciplinary such as mttlti-rigid dynamics, rigid-flexible coupling mechanics, aerodynamics, nonlinear vehicle kinematics and electronic controllability. This paper introduced current status of the development, study method and test means about the tractor-trailer lateral stability at home and abroad. The effects of use and structure parameters on the tractor-nailer lateral stability were discussed. At the same time, the lateral acceleration response to step input of steering angle was also analyzed in this paper.iastly, digital simnlation algorithm of the tractor-trailer dynamics was analyzed, and typical simulation models were presented.
