Aluminum-alloy achieves more application in automobile industry as a kind of lightweight material. Auto body structures experience complex loads and performance requirements differ greatly among these conditions. In order to integrate all mechanical properties into initial design of Aluminum-alloy structure, a new optimization method is provided. With the prototype of a steel trunk lid, a new design based on original structure space using material replacement, structure optimizing and formability validation method is put forward. New Aluminum-alloy trunk lid matches both the performance and manufacturability requirement with weight reduction of 41.6 %. This method provides a referable way for lightweight deign of aluminum-alloy trunk lid in initial design phase.
