Abstract: To address the issue of difficulty in designing and producing aluminum plate rear door inner plate caused by poor formability and ductility of aluminum plate material, complex shape of rear door inner plate, this paper introduced the simulation analysis of the formability of aluminum plate back door inner plates theoretically based on AutoForm finite element software. Through simulation analysis of different solutions, the final forming solution was determined which guided on-site production, and was verified in on-site debugging.
