摘　　要：以某型挖掘机的工作装置整体结构为研究对象,利用大型有限元分析软件ANSYS对挖掘机工作装置整体结构进行实体建模,采用接触分析法模拟销轴铰接处,对挖掘机典型工况下的强度、变形进行非线性计算,得出工作装置整体的应力云图、位移云图。分析结果表明:基于工作装置整体的有限元计算方法能极大地降低因构件简化带来的计算误差,减小连接处应力集中的影响,对工作装置的优化具有指导意义,也可为后期的试验测试、应变片位置的选取提供参考。Take the overall structure of an excavator working device as the research subject. The large-scale finite element analysis software ANSYS is used to set up a solid model of the overall structure of the working device. The contact analysis method is adopted to simulate the pin hinges. The nonlinear strength and deformation under the typical conditions are calculated to obtain the stress and displacement nephograms of the whole working device. The analytical results show that the finite element method based on the entire apparatus greatly reduces the computational error due to the component simplification and have little influence on stress concentration at the connection. Therefore, this method has the guiding significance for the optimization of working device and also provides a reference for the subsequent pilot test and the selection of strain gauge locations.
