摘　　要：将等效静态载荷法(ESLM)应用于平衡吊臂架系统的动态优化设计中,提出了平衡吊臂架系统动态拓扑优化后的部件构型。通过HyperWorks软件中的Motionview模块对平衡吊臂架系统进行动力学分析,得到了最大动态应力;运用等效静态载荷法,将动态载荷转化为等效静态载荷,进而在OptiStruct模块中实现平衡吊臂架系统在动应力约束下的拓扑优化设计;得到的动态优化设计结果为平衡吊臂架系统的结构设计提供了参考。The theory of equivalent static load method(ESLM)was applied to structural dynamic optimization design in balance hoist boom system,and to propose the component configuration of the boom system after dynamic topology optimization.Through dynamic analysis of the boom system using the commercial software of Motionview module in HyperWorks,the maximum dynamic stress was obtained.Dynamic loads were transformed into static loads with ESLM,then the topology optimization of balance hoist boom system was accomplished in HyperWorks environment at the constraint of stress.The results of dynamic optimization design can be applied to the balance hoist boom system design as a reference.
