摘　　要：飞机整体壁板和空心梁结构件作为飞机重要的承载件,朝着一体化、轻量化、高度集成化的方向发展。喷丸成形作为一种新兴、高效的成形工艺在飞机关键承力件的成形过程中得到了普遍的应用,然而在飞机整体壁板和空心梁结构件中出现了喷丸成形局部失稳以及凹坑回弹变形导致的表面不平整等许多亟待解决的技术问题,严重影响产品质量。本文综述了喷丸成形领域的研究现状,同时对目前所存在的关键技术问题进行了分析,为进一步开展飞机大型结构件喷丸成形研究提供新思路。As the important bearing parts of the aircraft,the monolithic panel and hollow beam structures are developing towards the direction of integration,light weight and high integration.The shot peening technology,as a new and efficient forming strengthening technology,has been widely used in the forming process of aircraft structural parts.There are many technical problems to be solved,such as partial instability of shot-peening forming and uneven surface caused by the rebound deformation of pits,which seriously affect the product quality.The research status of shot peening was reviewed,and the key technical problems were analyzed,which provided a new idea for further research on shot peening technology of large aircraft structural parts.
