摘　　要：引入Gim轮胎模型建立了四轮转向半挂汽车列车的非线性动力学模型。以零侧偏角为控制目标确定半挂汽车列车牵引车后轮转角。以建立的四轮转向半挂汽车列车非线性动力学模型为基础,采用数值不同的两种前轮转角输入,借助Matlab/Simulink仿真环境,对其运动规律进行时域仿真。仿真结果表明,高速时基于牵引车后轮转角的半挂汽车列车明显改善了车辆的操纵稳定性,且能在大前轮转角的情况下保证半挂汽车列车的稳定性。研究结果可为四轮转向半挂汽车列车操纵稳定性的优化及系统设计提供理论依据。The Gim tire model was adopted to set up the nonlinear four-wheel steering dynamic model of tractor-se mitrailer. Based on the established dynamic model, Simulation on a slip angle minimization four-wheel steering tractor-se mitrailer＇s time domain in Matlab/Simulink software environment was described. The consults suggest the handling and stability performance of a four-wheel steering tractor- semitrailer with high speed is better than the front wheel steering tractor-semitrailer. The conclusion can be useful for the system design of a four-wheel steering tractor-semitrailer and can direct the selection of vehicle design parameters.
