摘要
对某机型机身框与地板梁连接接头（耳片）的ＬＹ１２ＣＺ型材试样的中心孔进行了激光辐照处理，并作了疲劳对比实验，还对疲劳寿命Ｎｆ与激光辐照的比能量Ｑ值进行了研究。
In this paper, the fatigue experiments about the LY12CZ specimens of ear tieplate joining the frame and the ground plank beam in the plane by laser irradiation were conducted. According to the results of contrast experiments, the relation between fatigue life N f and specific power of laser irradiation was studied.
