Structural Analysis of the Forming Press for Airplane Stringers

Abstract: Due to the rapid growth of the world's midsize aircraft market, the complete aircraft industry has been expanding its global outsourcing. It is to respond to these changes in aircraft production paradigm through the development of forming systems in a intelligent stringer for mid-sized aircraft. During the machining for stringers, a large load is applied to the forming press and this causes stress in the structure of the forming press. At this time, excessive stress may cause plastic deformation of the forming press and lose the function. Therefore, this study is to secure the rigidity and safety through the structural analysis for the C-frame and the press head of the forming press.
