| Abstract: | To pre-estimate the formability of complex aircraft skin parts and study the key techniques of stress-cut and quality test, the post-processor of finite element simulation system-STRETCHFORM was developed, based on OpenGL(a library of 3D drawing), to assist the manufacture according to the stretch-forming feature of skin parts. The main function of modules, key technique including 3D graphic displaying algorithm, interactive data control as well as evaluation criterion of forming quality were analyzed and accomplished. Several examples were enumerated to demonstrate the good practicability of the system. |
