摘　　要：为解决液压挖掘机机械臂质量过大、性能受限的问题,研究引入挖掘力作为机械臂性能的评价方法,选择斗杆油缸闭锁时的机械臂受力情况作为仿真分析的基础,对其进行静力学强度分析,并使用导重法优化此状态的机械臂。研究结果表明:在优化后机械臂材料许用应力极限条件下,机械臂整体质量可以减少约21%,降低了挖掘机机械臂的生产成本。In order to solve the problem of excessive weight and limited performance of hydraulic excavator robotic arms,this study introduces excavation force as an evaluation method for the performance of robotic arms.The force situation of the robotic arm when the arm cylinder is locked is selected as the basis for simulation analysis,and static strength analysis is carried out.The guide weight method is used to optimize the robotic arm in this state.The research results show that under the allowable stress limit conditions of the optimized robotic arm material,the overall mass of the robotic arm can be reduced by about 21%,which can reduce the production cost of excavator robotic arms.
