摘　　要：以某公司自主研发的剪切机中齿轮齿条传动机构为研究对象,为验证其在工作过程中是否满足强度要求与疲劳寿命要求,采用Solidworks三维绘图软件建立其相应的实体装配模型,利用有限元分析软件ANSYS Workbench中Transient Structural模块与Fatigue Tool工具分别进行瞬态动力学分析与疲劳寿命分析。通过对其进行网格划分、材料属性设置、添加局部坐标系、约束自由度、施加转速、摩擦接触等一系列相应工况设置后,得出齿轮齿条在啮合传动过程中随时间历程变化的等效应力值、等效应变值、径向位移值以及齿条疲劳寿命等相应工作参数。通过计算结果得知,齿轮齿条在传递运动过程中均符合使用要求。In order to verify whether the pinion and rack transmission mechanism of a shearing machine developed by a company can meet the requirements of strength and fatigue life during its working process,the corresponding solid assembly model is established by solidworks 3D drawing software,and the Transient Structural module and Fatigue Tool in ANSYS Workbench are used for Transient dynamic analysis and Fatigue life analysis respectively.After a series of corresponding working conditions,such as meshing,adding local coordinate system,constraint degree of freedom,applying rotational speed,friction contact and so on,the maximum equivalent stress,the maximum equivalent strain,the maximum radial displacement and the fatigue life of the gear are obtained.The results show that the rack and gear can meet the requirements in the process of transmission.
