摘　　要：针对重型半挂汽车列车侧倾稳定性问题,在Matlab/simulink中建立了重型半挂汽车列车的数学模型及动力学仿真模型,并进行了转向盘阶跃转向输入下的牵引车驱动轴横向载荷转移仿真分析。仿真结果表明,牵引车驱动轴为侧倾稳定性危险车轴。通过分析不同车速和车辆结构参数时牵引车驱动轴载荷转移的变化情况,得到重型半挂汽车列车侧倾稳定性与车辆主要结构参数及不同车速间的关系。To address the roll stability of heavy-duty semitrailer train,the mathematical model and dynamic model of heavy-duty semitrailer train were established by using Matlab/simulink,and the transverse load transfer simulation of tractor driving axle was analyzed with the steering wheel step input.The results show that the driving axle of tractor is the dangerous axle of roll stability.The relation between roll stability and vehicle main structure parameters and different speeds was obtained by analyzing the load change of tractor driving axle with different speed and vehicle structure parameters.
