Abstract:

基于TruckSim建立了非线性半挂汽车列车整车仿真模型,以其作为控制方案仿真验证的平台。探讨了牵引车和半挂车独立差动制动控制对整车横摆运动的主动控制问题,控制方案分为顶层横摆力矩控制器和底层制动力分配器2部分,顶层控制器输出改善整车横向稳定性能的附加横摆力矩,底层制动力分配器合理分配各车轮的制动力来实现该附加横摆力矩,整个控制策略在Matlab-Simulink中实现。阐述了TruckSim与Simulink的联合仿真问题,搭建了TruckSim-Simulink联合仿真模型,通过湿滑路面上的单移线试验操作对控制策略进行了联合仿真分析,结果表明,TruckSim-Simulink联合仿真是进行半挂汽车列车稳定性控制策略分析评价的有效手段,所提出的控制方案能够显著改善整车的横摆稳定性和侧倾稳定性。
