摘　　要：应用ANSYS Workbench软件中的Transient Structural模块对自卸车举升机构进行了瞬态动力学仿真分析,得到了三角臂在工作过程中的受力情况以及最大应力随时间变化的情况。这种方法实现了在同一界面展现出整个机械机构的运动情况以及其中关键部件的应力分布和变化情况。The transient dynamics simulation of lifting mechanism of a dump truck is conducted by means of the transient structural module of ANSYS Workbench software in the paper. In the process of the simulation analysis, the two triangular plates are set as flexible bodies. As the results, the curves of force reaction over time on the joints of the triangular plate are obtained, so is the curve of maximum stress of the triangular plate over time. By this means, both the motion of the mechanism system and the time-varying stress distribution are showed in real time in the same simulation platform.
