Aluminum alloy fender mounting bracket design method and mounting bracket

Abstract

The invention discloses an aluminum alloy fender mounting bracket design method and a mounting bracket. The method comprises the following steps: S1, according to the boundary conditions of fender connection, judging whether the mounting bracket of a sheet metal part meets the design requirement or not, if so, stopping the design, and if not, carrying out the subsequent steps; s2, adopting an aluminum alloy die casting as a mounting support, and preliminarily determining structural parameters of the aluminum alloy die casting according to boundary conditions and stress modes of fender connection; and S3, importing the structural parameters obtained in the S2 into CAE for loading analysis, judging whether the aluminum alloy die casting determined in the S2 is reasonable or not according to the selectable strength range, the overall rigidity requirement and the modal requirement of the aluminum alloy material, if so, carrying out actual manufacturing and verification, and if not, returning the S2. The design scheme of the die-casting aluminum alloy can be rapidly determined under the condition that sheet metal parts are limited, and a powerful support is provided for rapid determination of project modeling and air inlet system arrangement.

Description

technical field [0001] The invention relates to the manufacture of auto parts, in particular to a design method of an aluminum alloy fender mounting bracket and the mounting bracket. Background technique [0002] With the development of the automobile industry, the requirements for the shape of the vehicle are continuously increasing, the requirements for the power of the vehicle are continuously increasing, the requirements for the size of the seating space are continuously increasing, the requirements for the driving experience are continuously increasing, and the precision requirements for the body manufacturing Therefore, the definition of boundaries in the design process of body sheet metal parts is becoming more and more stringent, and the difficulty of body design, especially the design of pickup truck engine compartments, is also increasing. [0003] First of all, the continuous improvement of styling requirements has led to the corner area of ​​the car being occupie...

AI Technical Summary

Problems solved by technology

[0005] 1. The accuracy of sheet metal stamping parts is low. Compared with aluminum alloy die-casting parts, multiple parts are welded or screwed together, resulting in tolerance accumulation and poor stability

[0006] 2. In order to ensure the accuracy of sheet metal stamping parts, welding is avoided. As a result, due to process limitations, the cross-sectional rigidity of the parts themselves is poor, which leads to the parts having to be thickened, resulting in heavier weight

[0007] 3. Due to the multiple "squeeze" of the headlights, front bumper, and fenders in the shape of the fenders and the front bumper mounting bracket area, and the air intake system requires "fresh and cool" air intake, the boundary is limited and it is difficult to design
