驱动桥桥壳建模及模型网格化处理

驱动桥壳是汽车上的主要零件之一,桥壳不仅是承载件还是传力件,同时又是主减速器、差速器及车轮传动装置的外壳。故驱动桥壳的质量极大影响了车辆的安全使用。随着经济发展,车辆保有量的日益增长,车辆不断向高速、轻量、低能耗和高性能发展。这要求桥壳不仅有足够的强度和刚度,还要求减轻质量以及必须对结构的振动特性分析。本文主要研究在对驱动桥壳简化及通过PROE建模后,如何在Hypermesh把模型网格化及对网格的修改和检查,本文的意义在于对驱动桥壳的有限元分析提供一个基础模型。

Modeling the Drive axle housing and Meshing the model

Driving axle shell is one of the main parts on cars.It is not only the load bearing part,the transmising force and torque part but also is the main reducer,differential and wheel transmission device shell.So the quality of driving axle shell greatly affect the safe use of vehicles. Along with the economical development and the increasing vehicle possession,vehicles are developing to high-speed,continuous lightweight,low energy consumption and high performance.This requires that axle housing not only has enough intensity and rigidity,also requires mass has been reduced to structure and the vibration characteristic must be analysed.This paper mainly research on how to use the Hypermesh meshing the model which is modeled by pro-E after simplifying the drive axle housing,and check the mesher and modify the mesher the meaning of this paper is to provide a foundation model to finite element analysis of drive axle housing.
