摘　　要：运用ADAMS软件建立牵引车整车模型,并进行稳态回转仿真分析,验证模型的正确性。通过对该车的侧倾状态进行理论分析,可知增大前悬架横向稳定杆刚度,保持后悬架横向稳定杆刚度不变,可以提高该车的不足转向。最后改变横向稳定杆参数,进行单移线仿真,得出不同参数对车身侧倾角的影响曲线,为优化该牵引车的操纵稳定性做准备。The tractor model was established by using ADAMS software, and then the steady-state turning simulation analysis was implemented to verify the correctness of the model. Through the theoretical analysis of the vehicle＇s roll state, the results show increasing the stiffness of the front suspension＇s lateral stabilizer bar while keeping the one of the rear can improve the vehicle＇s understeer. Finally, by changing parameters of the lateral stabilizer bar and conducting the single lane simulation, the influence curve of the vehicle＇s roll angle was obtained over different parameters. It provides a base for the optimization of the tractor＇ s handling stability.
