摘　　要：山地多功能履带式装载机是一款适合山地作业的小型农用机械,执行机构底座是关键部件之一,其性能直接影响装载机的作业能力。文中在分析装载机工作装置的工况和工作阻力的基础上,采用ADAMS动力学仿真软件得到了执行机构底座各铰接处在不同工况下的载荷。同时,采用ANSYS Workbench软件对执行机构底座进行了模态分析和静强度分析,并应用拓扑优化方法对其进行了轻量化设计。优化后底座质量减轻约44.15%,寿命约为19.4年,远高于现有的5~10年的设计寿命。The mountain-type multi-function crawler loader was a small size agricultural machine fit to mountain area.The actuator base was one of the key components of the loader and the operation capability of the loader was directly affected by the base performance.In this paper,based on the analysis of working condition and resistance of the crawler loader,the loads of articulated part at the base in the different conditions were obtained by ADAMS software.Meanwhile,modal analysis and static strength analysis were performed on the actuator base using ANSYS Workbench software.The lightweight design was performed using topology optimization.The weight of the optimized base decreased by 44.15%and the life was about 19.4 years,which was much higher than the original 5~10 years lifetime.
