摘　　要：为实现LW900K装载机工作装置动臂结构的性能评估,该文从装载机工作装置铰点载荷关系入手进行分析,并基于实测载荷的峰值载荷确定了铲斗收斗完成和卸料瞬间两个时刻的工作装置姿态为典型姿态;接着进行峰值载荷下的有限元仿真分析,即采用实体单元建立动臂结构有限元模型,确定载荷约束和位移约束条件等,最终得到两个典型姿态下实测峰值载荷对应的动臂结构强度安全系数分别为1.55和2.31。该型号装载机动臂结构强度富裕,可以进行一定的优化设计。In order to realize the performance evaluation of the boom structure of the working device of LW900K loader,through analysis of the load relationship at the hinge point of the working device of the loader,based on the peak load of the measured load,the working device attitude at the moment when the bucket rewinding is completed and the unloading moment are determined as the typical attitudes,and the finite element simulation analysis is carried out under the peak load.The solid unit is used to establish the finite element model of the moving arm structure,and the load constraints and displacement constraints are determined,so that the safety coefficients of the structural strength of the moving arm corresponding to the measured peak loads in the two typical attitudes are 1.55 and 2.31 respectively.The structural strength of this type of loading machine arm is affluent,and it can be optimized to a certain extent.
