Problems solved by technology

[0003] During the frontal collision of the vehicle, the front beam is the key sheet metal part. If the front beam is bent earlier, it is easy to cause insufficient crushing of the energy-absorbing box and the longitudinal beam, which will affect the deformation stability of the vehicle.

Abstract

A DOE-based optimization method for the anti-collision performance of the front bumper of the automobile belongs to the technical field of the structural design of the front bumper of the automobile. The peak value of the contact force of the roll-pressed front bumper is taken as the target, and the aluminum alloy front bumper with the largest weight reduction ratio is brought into the vehicle working condition for verification, the variable range and response are set and the optimization calculation is carried out. The optimal solution is obtained from the verification of the working conditions of the whole vehicle. The beneficial effect of the present invention is that the optimization method compares the simulation model with the test model, optimizes the simulation model, performs optimization calculations on multiple groups of variables and responses, and obtains the solution After repeated verification, the optimal solution is finally obtained. The efficiency of model establishment and optimization calculation is high, and the optimization result of the front beam is more reliable, which provides strong data support for the production design of the front beam and saves the company's product development. cost.

Description

technical field [0001] The invention relates to the technical field of structural design of an automobile front bumper, in particular to a method for optimizing the anti-collision performance of an automobile front bumper based on DOE. Background technique [0002] DOE (Design of experiment design) technology seeks key factors and controls related factors through quantitative analysis of product quality and process parameters. According to actual needs, identify and select different types of experimental designs, design experimental steps, find out how to control various influencing factors, and exchange for the greatest benefits with the least investment, so as to improve product quality and make it more popular in industrial production and engineering design. can play an important role. At the same time, DOE has the advantages of reducing the test cost, shortening the product test cycle and prolonging the product life. After a reasonable DOE, the aluminum alloy front bump...
