摘要
激光喷丸成形技术利用激光诱导冲击效应在壁板表层引入非均匀分布塑性应变,塑性层厚度是传统机械喷丸的5~10倍,能够有效克服传统壁板成形技术的不足,实现大型高加筋复杂型面带筋壁板的形性一体化成形制造。对激光喷丸成形技术的进展,从激光喷丸成形机理与规律、复杂型面激光喷丸成形几何形状控制、大型带筋壁板激光喷丸成形系统几个方面进行了综述;回顾了激光喷丸成形的发展脉络,介绍了大型壁板激光喷丸成形技术研究与应用现状,并对近几年激光喷丸成形技术的发展与趋势进行了梳理;指出了实现大型整体壁板激光喷丸成形应用的核心是掌握变形机理,解决成形工艺规划问题,并研制适用于大型整体壁板成形的工艺装置。
Laser peen forming(LPF)for large panel is a kind of deformation technology by inducing nonuniform plastic strain on surface using the laser-induced shock wave.The depth of plastic strain of LPF is five to ten times of the traditional shot peening,hence it can be applied for the manufacture of large panel with high ribs and complex geometry.This paper presents a recent progress of LPF from following aspect:the mechanism of bending deformation of LPF,the shape controlling of LPF for complex geometry and the apparatuses developed for LPF.The background and research status quo are summarized,and the advises are given for the research of LPF.The most important for LPF of large panel is acquainting the bending mechanism and the process optimization and developing apparatus for LPF.
