基于熵权-TOPSIS的CFRP电池箱体铺层优化设计
Lager optimization design of CFRP battery-pack enclosure using entropy-based TOPSIS approach
摘要
Abstract
In order to achieve lightweight design for a new energy vehicle battery box,a lightweight and high-strength carbon fiber reinforced plastic(CFRP)was used to replace the structural material.The entropy-based TOPSIS method based on orthogonal test table was utilized for multi-objective layup optimization design.The me-chanical properties of CFRP laminates were predicted using the Digimat commercial software,and their correctness was verified through mechanical performance tests.Based on laminate design criteria and equal stiffness design prin-ciples,the preliminary structural plan for the CFRP battery box was determined.Finally,the laminate layering was optimized with the goal of minimizing deformation and maximizing the first-order mode,resulting in the best per-formance CFRP battery box structure.The research findings indicate that the optimized CFRP battery box shell is 46.74%lighter than the original metal structure,and the overall performance of the battery box structure is also im-proved.关键词
