Abstract : in this paper , the effect of pre - stress on peen - forming is studied by experiments , the results show that pre - stress can change the relationship between pre - deformation and pre - stress shot peen deformation , and that 0 . 05 % 0 . 1 % pre - strain is comparetively suitable to improve the spanwise rectilinearity of shot peen - forming configuration surface 文摘:对预应力喷丸成形进行了试验研究,指出预应力可以改变其对应的预变形与预应力喷丸变形之间的大小关系,在以改善喷丸型面纵向直线度为主要目的的预应力喷丸成形中,预应变取值0 . 5 / 1000 1 / 1000较为适宜。
