摘　　要：针对前后车桥均为双纵臂形式的电动工程车辆悬架系统,文中通过Solid Works建立其三维模型,利用ADAMS软件对模型进行动力学仿真分析。通过改变悬架系统的双纵臂铰点布置,分析各铰接点的受力变化、车辆转向轨迹的变化及车辆转向时的侧倾角大小,可得出悬架系统铰点位置变化对整车动态特性的影响,分析结果可用于车辆悬架系统的优化和改进。As for the electric-engineering vehicle＇s suspension system with both front and rear axles featuring the double trailing arms, this article has established its three-dimensional model through Solid Works, and employed ADAMS software to carry out the dynamic simulation analysis of the model. It, by changing the layout of the hinge point of the suspension system＇s double trailing arms and analyzing the change of the force of each hinge point, the change of the vehicle＇s turning trajectories,and the magnitude of the roll angle when the vehicle is turning, has concluded that any change in the location of the suspension system＇s hinge point exerts dynamic influence on the whole vehicle＇s characteristics. The analysis results can be used for the optimization and improvement of the vehicle＇s suspension system.
