Shot peening is a key problem that puzzles the precise forming of large integral wing panels. It is difficult to predict and control the development of elongation only considering shot peening forming and strengthening. This paper analyses the factors that affecting the precision control of shot peening elongation from the aspects of slab processing technology

processing environment and shot peening technology comprehensively

and summarizes the research method on shot peening extension prediction and slab development. These research methods provide systematic technical guidance and theoretical reference for solving the fluctuation of shot peening forming dimension extension

and is of great significance for improving the forming efficiency and accuracy of integral wing panels.
