Application of the Robust Approach and Finite Element Analysis in Door System Static Design

摘要

The robust design approach based on Taguchi′s design of experiment (DOE) coupled with the traditional finite element analysis (FEA) is applied to the static design of a sedan door.This method aims at shortening the design period,reducing the calculation cost and improving the competitive competence.First,the performance requirements,the control factors and the corresponding levels are determined to design a DOE table.Second,based on the schemes from the DOE table,sensitive control factors are distinguished from the results of the FEA method.Finally,the optimum design is chosen after comparisons and analyses of these performance response graphs.Performance results of the optimum design indicate that the application of the robust approach and FEA can greatly improve the quality of the door system,satisfy the requirements of products,underline the design purpose and shorten the design period.
