摘　　要：喷丸延展问题一直是困扰大型整体机翼壁板精确成形的关键问题,仅考虑喷丸成形、强化工艺很难准确预测延展量并控制其发展,从板坯加工工艺、加工环境、喷丸工艺等角度综合分析了影响延展量精度控制的因素,并总结了关于喷丸延展预测、板坯展开的研究方法,为解决喷丸成形尺寸延展波动问题提供了系统的技术指导和理论参考,对于整体机翼壁板成形效率和精度的提高具有重要意义。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.
