Abstract：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.
