Abstract：

Owing to the large size and low roughness, the forming process of large sheet metal parts of aircraft is difficult. The shape and structure were optimized after increasing the corners and decreasing the length of adding straps based on the analysis of the part structure and assemble requirement. The reasonable fabrication technology and a set of deformation proof measures were defined using deep drawing method that improved the forming approach and the accuracy. By finite numerical simulation, theoretical computation and experiment, profile dimensions of the semi finished products were optimized, the reasonable tooling structure and the best BHP value were determined.Thus the precise forming requirement is satisfied.
