现代经济型轿车大都采用前轮驱动的布置型式，等速万向节是其中的关键部件之一。目前，汽车传动系统中使用最多的是球笼式和三枢轴式等速万向节连接在一起组成的等速驱动装置。由于等速万向节结构复杂、加工制造精度高、难度大，目前我国主要是引进国外专用设备生产，投资费用很大。为此，国家将等速万向节列为重点扶持的汽车关键零部件项目之一。
本文以国内某厂家发动机前置前驱动轿车等速驱动轴中的球笼式等速万向节和三枢轴式万向节为研究对象，利用三维重构技术建立等速万向节的三维实体模型，继而应用理论计算、试验测量相结合的手段，围绕等速万向节内部接触应力展开了研究。

e constant velocity driving device which is composed of ball basket constant velocity universal joint together with constant velocity universal joint with pivot is used by automobile transmission system mostly.Because the structure of constant velocity universal joint is very complicated,process the precision of making is high,and difficulty of making is large.Our country introduces foreign special-purpose device mainly at present,it is very expensive to make the investment.For this reason,our country have regard constant velocity universal joint as one of the key part project to support especially.
The ball-cage type and the three pivot shaft type constant velocity joints of theconstant velocity drive shaft on the F-F type car of a certain domestic factory wereregarded as research objects.The 3D models of the constant velocity joints werebuilt by using 3D re-created technology,then the finite element models of theconstant velocity joints were built by using ANSYS software,then the authorcarries out the study on the inner contact stress of the constant velocity joints bymeans of the connection of the finite element analysis,theoretic calculation and thetest.

第1章绪论
1.1 万向节的应用
在机械领域里，有一个很重要的基础件，称为万向节。它是连接轴与轴之间的联轴节，主要应用在两个轴之间不同轴或不同心的场合。与其它的齿轮传动、带传动、链传动机构相比，万向节传动机构有着独特的、其它机构不能代替的优点，当需要将一根轴上的扭矩或传动以较大的轴间夹角传到相距较远、且角度可能变化的另一根轴时，往往只能选择万向节传动机构来实现。其作用在航空航天、机床、机械、尤其是汽车领域非常重要。随着汽车工业100多年的发展历史，万向节的结构形式也得到了很快的发展。福特嘉年华二厢报价
