JIU JIANG UNIVERSITY 毕 业 论 文 题 目 汽车驱动桥壳UG建模及 有限元分析 英文题目 Modeling by UG and Finite Element Analyzing of Automobile Drive Axle Housing 院 系 机械与材料工程学院 专 业 车辆工程 姓 名 班 级 指导教师 摘 要 本篇毕业设计（论文）题目是《汽车驱动桥壳建模UG及有限元分析》。作为汽车的主要承载件和传力件，驱动桥壳承受了载货汽车满载时的大部分载荷，而且还承受由驱动车轮传递过来的驱动力、制动力、侧向力等，并经过悬架系统传递给车架和车身。因此，驱动桥壳的研究对于整车性能的控制是很重要的。 本课题以重型货车驱动桥壳为对象，详细论述了从UG软件中的参数化建模，到ANSYS中有限元模型的建立、边界条件的施加等研究。并且通过对桥壳在工况下的静力分析和模态分析，直观得到了驱动桥壳在各对应工况的应力分布及变形情况。从而保证强度刚度与动态性能要求的前提下，为桥壳设计提出可行的措施和建议。 Abstract This graduation project entitled “Modeling and Finite Element Analyzing of Automobile Drive Axle Housing”. As the mainly carrying and passing components of the vehicle, the automobile drive axle housing supports the weight of vehicle, and transfer the weight to the wheel. Through the drive axle housing, the driving force, braking force and lateral force act on the wheel transfer to the suspension system, frame and carriage. The article studies based on heavy truck driver axle ，discusses in detail from the UG software parametric modeling, establish of ANSYS FEM model, and the boundary conditions imposed, etc. And through drive axle housing of the different main conditions of static analysis and modal analysis, it can access the stress distribution and deformation in the corresponding status of drive axle directly. Thus, under the premise of ensuring the strength of drive axle housing, stiffness and dynamic performance requirements, the analysis can raise feasible measures and recommendations in drive axle housing design.Plans to establish thet hree---dimensional model by UG, to make all kinds of emulation analysis by Ansys. 【Key words】前 言 1 第一章 绪论 2 1.1 汽车桥壳的分类 21.2 国内外研究现状 3 1.3 有限元法及其理论 5 1.4 ansys软件介绍 7 1.5 研究意义及主要内容 9 1.
