摘　　要：建立了包含非线性轮胎模型和柔性车身的半挂汽车列车数学模型,用于分析其侧倾稳定性,防止侧翻的发生。在Matlab/Simulink中搭建了仿真模型。给整车以转向盘角阶跃输入,分析了不同车速和结构参数下半挂汽车列车的各轴载荷转移变化情况,得出半挂汽车列车结构参数与侧倾稳定性的内在联系,为汽车设计与控制侧翻提供了参考与依据。In order to analyze roll stability of tractor-semitrailer and prevent the occurrence of rollover,the flexible frame mathematical model with nonlinear type model is established.Then the simulation model is established in Matlab/Simulink.With step input of the front wheel steering angle,the difference of the load transfer at all axle in different speed and structure parameters is analyzed.The relationship between roll stability and structure parameters or speed is obtained.It provides reference for its design and prevents the occurrence of rollover.
