摘　　要：采用ANSYS有限元方法对减速器输出轴进行分析计算。利用三维软件SolidWorks建立轴的实体模型,并将模型导入ANSYS中,选用Solid45作为轴的单元,得到轴的有限元模型。然后在轴颈处添加刚性约束,输出端轴头处施加扭矩,齿轮处的键槽处施加载荷,完成输出轴的静强度分析和模态分析。有限元分析结果表明,该输出轴满足轴的强度、刚度和振动稳定性要求。In this thesis, finite element analysis is performed to calculate the output shaft of a reducer.The 3-D entity model of the axle is set up by using the Solid Works software.Choosing the element of Solid45, the finite element model is set up through the software ANSYS.Then the rigid restrictions are established on the axle necks, a torque is applied on shaft head, loads are applied on key way of gear.Then static strength analysis and modal analysis of the output shaft of a reducer are com-pleted.The results show that the output shaft meets the demand of the strength, stiffness and vibration stability.
