Stability Analysis about Steering Wheel Angle Step input Controllability Based on Simulation Tractor-Semitrailer

基于任意载荷分布的非线性轮胎模型,应用汽车列车动力学仿真软件ARCSIM,分析了半挂汽车列车在转向盘转角阶跃输入时的转向特性。通过在不同车速、不同结构参数等条件下的仿真计算,揭示了半挂汽车列车的转向特性与车速、结构参数之间的内在联系,给出了半挂汽车列车转向特性在这些条件下的表现特征,为半挂汽车列车操纵稳定性分析提供了参考和借鉴。

Based on nonlinear tire model, the ARCSIM on articulated vehicle dynamics simulator is used to analyze the vehicle steering characteristics with the step angle input of steering wheel. It is found that the steering characteristics are different when the velocity and configuration parameter are different, and the relationship between steering characteristics and velocity, configuration parameter is presented, so it provides reference for the analysis of controllability and stability.
