摘　　要：以某液压挖掘机工作装置为研究对象,针对现有动臂、斗杆独立简化分析存在的问题,基于斗杆挖掘工况对动臂进行应力测试。运用三维建模软件Catia以及有限元分析软件Hypermesh、Abaqus对工作装置整体进行几何建模与有限元结构应力分析,用实测应力值验证工作装置有限元模型的有效性。结果表明,实测应力与有限元计算应力变化趋势一致,反映了工作装置整体的静应力特性,为工作装置进一步结构优化设计提供了参考依据。Take the hydraulic excavator working device as a research object, aimed at the problem of swing arm and bucket arm separate simple analyze, and carry out stress test on the swing arm based on bucket arm excavating condition. Uses three dimensional modeling software and finite element analysis software to build geometric model, analyze structural stress for working device, and verify the validity of the finite element model of working device with the measured stress value. Results show that the variation trend of measured stress and finite element stress is consistent. Finite element model reflect the overall static stress characteristics of the working device,which provides the reference for further structural optimization design of the working device.
