新能源汽车等速万向轴总成力学性能分析(含CAD图)(开题报告,外文翻译,文献摘要,论文说明书26000字,CAD图3张)
在现代汽车结构中，万向传动装置起到了承上启下的作用，得到了广泛的应用。万向传动装置一般由万向节和传动轴组成，特别关于长轴距的汽车，偶尔还应该改装加上中间支撑。其功用是实现汽车上任何一对轴线相交且相对位置经常变化的转轴之间的动力传递。
本文主要内容是针对新能源汽车的等速万向轴总成进行相关的力学性能分析，主要包括了以下几个部分：关于等速万向节、驱动半轴以及其一同组成的等速万向轴总成的结构和功能的相关介绍；关于等速万向轴和驱动半轴的设计方法，其中对球笼式等速万向轴进行了详尽的设计工作；关于ABAQUS有限元分析软件在于等速万向轴总成力学性能分析方面的应用；利用ABAQUS软件针对等速万向轴总成进行有限元分析，主要进行力学性能分析，包括应力分析、应变分析以及位移分析。

ABSTRACT
In the modern automobile structure, the universal joint transmission device has played a role in the connection and has been widely used. The universal joint transmission generally consists of a universal joint and a drive shaft, especially for long-wheelbase vehicles, and occasionally should be modified with intermediate support. Its function is to achieve the power transmission between any pair of axes on the car that intersect with each other and whose relative position changes frequently.
The main content of this paper is about the mechanical performance analysis of the constant-speed universal joint shaft assembly of the new energy vehicle, which mainly includes the following parts: the constant velocity universal joint, the driving half shaft and the constant velocity universal joint shaft assembly thereof. Introduction to structure and function; design method for constant velocity universal joint shaft and drive half shaft, in which the ball cage type constant velocity universal joint shaft is designed in detail; the ABAQUS software lies in the constant velocity universal joint shaft assembly mechanics Application of performance analysis; using ABAQUS software for finite element analysis of constant velocity universal joint shaft assembly, mainly for mechanical performance analysis, including stress analysis, strain analysis and displacement analysis; finally, the whole graduation design is summarized.

Key words:new energy vehicles ，onstant velocity universal joint shaft,，mechanical property analysis，ABAQUS，finite element analysis
