摘　　要：以汽车高速轴为研究对象,基于Solidworks软件,对高速轴建立三维实体模型,并将模型无缝导入ANSYS Workbench 13.0;基于ANSYS Workbench 13.0对高速轴的材料及属性进行定义,对高速轴进行网格划分以建立有限元模型,并添加与实际工况相同的载荷与约束;借助ANSYS Workbench 13.0对高速轴在汽车加速瞬间的动力学特性进行数值模拟分析,获得高速轴在变载荷下的总变形分布云图、应力分布云图和应变分布云图;对有限元模拟结果进行分析可以看出高速轴的轴肩在汽车加速瞬间的总变形和应力变化很大。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.
