摆线针轮传动接触非线性疲劳寿命分析
|
摘要
基于摆线针轮传动啮合原理和赫兹接触理论,对RV减速器中摆线针轮啮合接触时的应力分布特点和最大啮合接触应力进行了理论分析和非线性有限元分析,对比两种方法得到的摆线针轮最大接触应力基本一致,均小于摆线针轮的齿面接触疲劳极限,验证了该有限元模型的有效性和可参考性,为进一步的疲劳寿命预测和优化设计提供理论基础和有效数值分析方法。根据有限元静力分析结果,采用MSC.Patran对摆线针轮的疲劳寿命进行分析和预测。
Based on the meshing principle of cycloid needle wheel transmission and Hertz contact theory, the theoretical analysis and nonlinear finite element analysis of the stress distribution characteristics and the maximum meshing contact stress of cycloidal pin wheel in RV reducer are carried out. The maximum contact stress of the cycloid needle wheel is nearly the same as that of the two methods, all of which are less than the cycloid. The contact fatigue limit of the tooth surface of the needle wheel has proved the validity and reference of the finite element model, which provides a theoretical basis and effective numerical analysis method for further fatigue life prediction and optimization design. According to the results of finite element static analysis, the fatigue life of cycloidal pin wheel is analyzed and predicted in MSC.Patran.
