摘　　要：针对RV减速器的结构特点,定义了几何特征参数,并结合摆线轮、渐开线齿轮的齿廓方程,采用ANSYS参数化设计语言APDL与用户界面设计语言UIDL对ANSYS进行二次开发,实现了RV减速器整机的参数化建模,并采用Pro/E进行运动学仿真对该模型进行了验证;对RV-40E的参数化模型进行了参数化的模态分析,结果与试验模态达到了很好的吻合程度;通过改变模型参数,研究了RV减速器1阶固有频率的影响因素,得到了关键参数的影响曲线,为动态特性的提高提供了依据。提出的参数化建模方法,减少了对RV减速器进行各种有限元分析时所需的建模工作量,避免了重复建模,极大地提高了有限元分析的效率。其在模态分析方面的应用也为ANSYS平台下RV减速器的参数化建模与有限元分析一体化奠定了基础。The geometric parameters are defined according to structural features of RV reducer and the secondary development of ANSYS for parametric modeling is finished by using ANSYS parametric design language（ APDL） and user interface design language（ UIDL） based on tooth profile equation of curtate cycloid and involute. The parametric modeling is proved by using the kinematic simulation through Pro / E. The modal analysis of RV- 40 E is finished and the results is coincided with the experimental modal analysis results. By changing the parameter,a study about influence factors of the first order natural frequency is conducted. The influence curve is obtained and it can become the basis of improving dynamic property. The method of parametric modeling of RV reducer could improve the efficiency of finite element analysis by reducing the workload of modeling and avoiding repeated modeling. The application in modal analysis has laid the foundation for the integration of parametric modeling and finite analysis of RV reducer.
