英文摘要：

Taking the high speed shaft of the automobile as the research object, based on the Solidworks software, the 3D solid model of the high speed shaft was built and the model was seamlessly imported into ANSYS Workbench 13.0. Based on ANSYS Workbench 13.0, the material and attributes of the high speed shaft were defined. The high speed shaft was meshed to establish the finite element model, and adding the same load and constraint as the actual working conditions. Then, the dynamic characteristics of the high speed shaft at the moment of acceleration were numerically simulated by means of ANSYS Workbench 13.0. The total deformation distribution nephogram, stress distribution nephogram and strain distribution nephogram of the high speed shaft under variable loads were obtained. The analysis of the finite element simulation results showed that the total deformation and stress of the shaft shoulder in the acceleration moment of the high speed shaft changed greatly.
