【摘要】 在合理的理论假设基础上建立了较为精细的牵引车-半挂车的整车动力学仿真模型。应用此模型,针对6×4牵引车拖挂2轴半挂车列车的折叠、甩尾、倾翻及转向瞬态响应进行了仿真,并对各工况的特点进行了分析。仿真结果表明该模型能够很好地模拟车辆在各种危险工况下的运动状态,从而为进一步研究牵引车-半挂车列车的性能特点提供了很好的工具。更多还原

【Abstract】 Based on reasonable theoretical hypotheses,this paper presents a math model for tractor-smitrailer combination.With this model,the typical conditions of a tractor-smitrailer combination,including jackknifing,swinging,rollover and transient response to cornering,are simulated with their characteristics analyzed.Simulation results indicate that the model can well predict the behavior of the vehicle under various dangerous conditions.更多还原
