| 英文摘要: |
| The paper aims to solve the problems of cracking and excessive thinning during stamping and forming of parts through synergistically optimizing structure of aluminum alloy outer door panel and parameters of stamping forming process. This study optimized the size and shape parameters of the door from the perspectives of material flow and stress distribution, and used the finite element analysis software AutoForm to obtain a set of optimal stamping process parameter combinations, which were finally verified by factory trial production. The stamping formability of the aluminum alloy outer door panel was greatly improved. It solved the cracking of the door outer panel during stamping and forming. The research results have important guiding significance for the structural design and stamping process of large body panels. |
