关于轻型汽车驱动桥壳有限元分析

摘要  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。 本文以轻型载货汽车驱动桥壳为研究对象?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。并且通过对桥壳在四种主要工况下的静力分析和模态分析?直观地得到了驱动桥壳在各对应工况的应力分布及变形情况。从而在保证驱动桥壳强度、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  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. This article studies based on light truck driver axle of QX1060, 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 four 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.  Keywords?Finite element method?UG?ANSYS Workbench?Drive axle housing?Static analysis?Modal analysis
