Finite Element Analysis of Bending Performance of Aluminum Alloy Wheel hub

汽车轮毂是汽车上的重要旋转部件,文章以汽车轮毂为研究对象,对其弯曲性能进行有限元分析,为其轻量化设计和结构优化提供理论基础。汽车轮毂的轻量化设计需从材料和结构两个方面考虑,在当前的汽车行业,铝合金是汽车轮毂的最佳选择材料;结构方面,文章利用CATIA三维设计软件对汽车轮毂进行简单的造型设计,然后运用ANSYS有限元软件,对轮毂的弯曲性能进行了有限元分析,研究了轮毂的应力分布情况,在保证其最大应力值远小于铝合金轮毂许用应力的情况下,对轮毂的结构优化设计提供了理论依据。

The automobile wheel hub is an important rotating component in the automobile.This paper takes the automobile wheel hub as the research object and conducts finite element analysis on its bending performance,which provides a theoretical basis for its lightweight design and structural optimization.The lightweight design of automobile wheels needs to be considered in terms of materials and structure.In the current automotive industry,aluminum alloy is the best choice for automobile wheels.In terms of structure,this paper uses CATIA three-dimensional design software to carry out simple design of automobile wheels.Then,using ANSYS finite element software,the finite element analysis of the bending performance of the hub is carried out,and the stress distribution of the hub is studied.The structure optimization of the hub is ensured when the maximum stress value is much smaller than the allowable stress of the aluminum alloy wheel hub.The design provides a theoretical basis.
