摘要

本文对一种新型预折纹吸能管进行了多样性可竞争解DCD（Diverse Competitive Design）对偶优化设计。文中把DCD对偶优化算法与Kriging代理模型相结合，考虑了汽车预折纹吸能管峰值载荷和比吸能，对折纹管的形状进行了参数优化设计。优化结果给出了在这组对偶DCD优化列式下不同折纹管最优设计的构型，性能及变形模式，说明了多样性可竞争解设计在工程中的意义。

Abstract

This paper presents the Diverse Competitive Design (DCD) for a new pre-fold energy absorption tube. This study aims to optimize the geometric parameters to minimize the specific energy absorption and maximize peak force for the energy absorption tube by combining the pair of diverse competitive design optimization with Kriging surrogate together. Different configurations, behaviors and deformation patterns are obtained for the DCD and dual DCD optimization problems. The results illustrate the significance of the diverse competitive designs in the actual engineering field.
