Embodiment Construction

[0017] The optimization and design method of the automobile wheel hub of the present invention comprises the following steps:

[0018] a) Automobile hub solid modeling design: use UG software to carry out parametric three-dimensional modeling design for automobile hub, and simplify the geometric model in UG software, simplify the geometric features that have little influence on analysis and difficult mesh division, and simplify the wheel core The bolt seat bears the compressive stress exerted by the bolt, which simplifies the characteristics of the large number of grids caused by the division of the non-examined area for analysis;

[0019] b) Mesh division of the geometric model of the hub: import the simplified geometric model in step a) into Hypermesh software for grid division, use tetrahedron second-order elements to divide the mesh, and tetrahedron second-order elements to divide the mesh It has the same accuracy as the hexahedron first-order unit grid, and the unit size ...

Abstract

The invention discloses a method for optimizing and designing an automobile hub. The method comprises the steps of designing the style for an automobile hub body, carrying out mesh generation on a hub geometric model, establishing a finite element model, processing a load and boundary conditions of the hub, analyzing the automobile hub structural performance and optimizing and designing the hub structure. According to the method, the statics, dynamics analog simulation analysis and fatigue life prediction are carried out on the hub based on the finite element analysis, the hub structure is reasonably arranged, and the potential problem is found out as soon as possible and is modified pertinently. The using quantity of aluminum alloy materials is reduced on the premise that enough strength is guaranteed, the materials at the positions with the excessive strength are fully utilized, the product structure is more optimal and reasonable, the weight is reduced, the product quality is improved, the research, development and design period is shortened, production cost is reduced, and the enterprise market competitiveness is enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of automobile wheel hub design, in particular to an optimization and design method of an automobile wheel hub. 【Background technique】 [0002] The automobile hub is not only an important structural part of the automobile, but also an appearance part and a safety part. In addition to its light weight, it also needs to be beautiful and firm. It is difficult to find the best balance point through traditional empirical design methods, but designing with computer-aided engineering (CAE) methods is a very effective means to solve this problem. How to reduce the weight of the wheel hub, shorten the product development cycle, and reduce the production cost under the premise of ensuring the performance and use requirements of the wheel hub has become one of the problems that need to be solved urgently in my country's automobile design and manufacturing industry. . 【Content of invention】 [0003] The purpose of ...
