摘 要

驱动桥的零件很多,结构复杂. 驱动桥作为汽车四大总成之一，它的性能的好坏直接影响整车性能，

而对于载重汽车显得尤为重要。本文主要是关于某农用运输车驱动桥设计及静强度分析.
    首先,对驱动桥的设计特点结构特点进行了简单的说明.运用传统力学的计算方法和已知驱动桥设

计参数进行计算,在设计过程中对驱动桥及各总成的结构进行具体选择,并且对其的强度进行详细的校

核.然后利用AutoCAD建立二维图;结合驱动桥的结构特点和工作原理运用三维建模软件Catia建立三维

模型.最后应用Catia中的分析模块对驱动桥壳进行静强度分析.

Abstract

 Driving axle's components are many, the structure is complex.  Bridge drive a vehicle

with one of the four trains, its performance will have a direct impact on vehicle

performance, and it is particularly important for the truck.  This article is mainly

about the design and the static strength analysis of some agricultural use transport

vehicle driving axle
First, has made the simple explanation to driving axle's design feature Structural

feature, Carry on the computation using the traditional mechanics's computational method

and the known driving axle design variable,Carries on the concrete choice in the design

process to the driving axle and various units' structure, And carries on the detailed

examination to its intensity. Then using AutoCAD setup two dimensional plot; Unifies

driving axle's unique feature and principle of work utilization three dimensional

modelling software Catia setup the three-dimensional model. Finally make the static

strength analysis using the analysis module in Catia to the driving axle shell.
