New Developments in the Study of Skin Stretch Forming Process

As a core component of the aerodynamic shape of aircraft and high-speed trains, the forming quality of the skin directly affects performance and cost. In recent years, the skin stretch forming process has achieved rapid development through multiphysics coupling simulation, multi-factor parameter optimization, and innovation in intelligent equipment. This paper reviews the new research progress from four dimensions: numerical simulation technology, process parameter optimization, process equipment innovation, and the application of new technologies in the stretch forming process of skins. It also proposes future research directions.
