摘要
汽车轮边减速器是重型汽车的重要运动件，减速器的好坏很大程度上作用着重型汽车的动力学和稳定性。本文以行星齿轮减速器为研究对象。首先，分析了该减速器的结构形式，进行了正确的选择。
其次，通过CATIA三维图形软件绘制出行星齿轮轮边减速器机构的CAD图形，并完成零件装配。然后通过通用接口导入到ADAMS虚拟样机,在ADAMS里面对各个零件添加正确的约束及运动副并进行仿真得到运动特性和动力学特性。
通过CATIA与ANSYS的通用接口将模型导入到ANSYS软件里面，对该模型进行处理划分网格。利用ANSYS里面的模态分析处理程序，对该连杆进行模态分析，从而得到构件的模态变形图和沿不通方向的位移场分布图。

Abstract
 Automotive wheel reducer is an important heavy vehicles moving parts, reducer good or bad largely focused on the role of cars dynamics and stability. In this paper, the planetary gear reducer for the study. First, the analysis of the reducer structure, were the right choice.
Secondly, through the CATIA 3D graphics software draw planetary gear wheel reducer institutions CAD drawings, and complete parts assembly. Then through a common interface into ADAMS virtual prototype, in which the various parts ADAMS add the correct constraints and deputy campaign and conduct simulated motion characteristics and dynamics.
CATIA and ANSYS through a common interface to import the model into ANSYS software inside, the model is processed mesh. Using ANSYS modal analysis inside the handler, modal analysis of the connecting rod, resulting in component modal deformation maps and directions along the barrier displacement field distribution.
