对 LY12 ( 2 0 2 4 ) T62薄板铆钉孔进行激光冲击处理 ,装配后与未经激光冲击处理的铆接结构进行随机谱疲劳寿命对比 ,发现铆接结构的疲劳性能在冲击后有稳定地提高。。
The LY12 (2024) T62 lamellar rivet hole was subjected to laser shock treatment, and compared with the random spectrum fatigue life of the riveted structure without laser impacting after assembly, the fatigue property of the riveted structure was found to be steadily improved after impact. .
