Study on Numerical Simulation for Stretch-Forming Air Intake Skin

The stretch-forming of skin is an important process in the field of aerospace manufacturing industry, whose advanced extent is one of important marks for judging the aircraft manufacturing capability and level of one country. Therefore, the development of stretch forming technology is of great significance for our national aviation manufacturing industry. The purpose of this paper is to apply the finite element software Marc/Mentat for analyzing and studying the problems existing in the present production process of intake skin stretch-forming by combining the numerical simulation with the productive test verification method and to put forward the solving solution, thus determining the process concept and process parameters for production of part.
