Abstract

Aiming at the problem that the study of vehicle door lightweight is mostly the single-objective optimization, and do not take unconcern factors into consideration, the vehicle door lightweight research of multi-objective optimization and robustness analysis is conducted. Firstly, the sensitivity analysis is used to pick out vehicle door parts which have more contribution toward vehicle door performance as the design variables, then establishing the approximate models of each vehicle door response. Secondly, taking vehicle door torsion stiffness, drooping stiffness, lateral bending stiffness and dent resistance as the constrains, taking the minimum mass and maximum first three modal frequency of vehicle door as targets, the multi-objective optimization is conducted by using the NSGA- , then the quality level and reliability analysis is carried out by using Monte Carlo simulation. Thirdly, the vehicle door not only realize the lightweight, reducing 0.97kg, but also has the good robustness.
