摘　　要：以履带式装载机执行机构千秋架为分析对象,对其进行动态仿真、模态分析和强度分析,得出千秋架的载荷谱、应力云图和位移云图。在保证原有强度和性能的基础上,根据拓扑优化方法对其进行轻量化优化设计。优化结果表明,千秋架的重量减轻了40.85%,同时千秋架的综合性能也得到了提高,实现了千秋架的轻量化设计。In this paper,a connecting rod of caterpillar loader actuators was taken for analysis,then the dynamic simulation and stress ＆ displacement nephogram was obtained by model and strength analysis. In order to ensure the original slrength and performance,a lightweight design was carried out according to the Topology density cloud .Analysis resuhs showed that lhe weight of the connecting rod was reduced by 40.85% ,the overall performance was improved also ,the lightweight design was realized.
