摘　　要：为实现对重载机械软启动装置性能的准确评估,将虚拟样机技术应用于该产品的设计开发中。在三维建模软件Pro/Engineer环境下构建族表式及参数式零件库,并混合运用由顶向下和由底向上两种装配模式完成了该软启动装置的虚拟样机模型。采用多刚体动力学软件ADAMS分别完成了运动学及动力学仿真分析,得出了控制电机与主电机的最佳功率比。仿真结果验证了机构设计的合理性与可靠性。In order to estimate the performance of soft-starting device of heavy-duty machinery correctly virtual prototyping is introduced in the process of designing and developing. Two types of component library were built in the environment of Pro/Engineer, which are design parameter type and family table type respectively, By using the assembly model of Top to Bottom and Bottom to Top the virtual prototye of soft-starting device is completed. Kinematic and dynamic simulations are performed. At last the power ratio of main motor and controlling one are obtained, The simualtion resluts show that the design principle is correct and the structure is credible.
