ABSTRACT

Due to the rapid growth of the 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 the forming systems. Aircraft structures are mostly produced, based on cutting or plastic working to minimize change of properties due to thermal strain. Forming press is used for bending stringers, which are main wing structures of aircrafts, and, precise control of press head displacement is essential to ensure high quality of stringers. Therefore, this study attempted to predict plastic deformation of the stringer according to the press head by using the finite element method, and to use the result for the forming press control.
