Abstract本发明公开了一种整体叶盘激光冲击强化方法,该方法首先将整体叶盘通过夹具安装在轨迹机器人末端的法兰盘上,然后将光路系统依次设定为光路三(9)工作、光路一(15)工作、光路四(10)工作、光路二(14)工作、光路四(10)工作和光路二(14)工作,依次分别对整体叶盘叶片的叶背后缘区域(3)、叶盆前缘区域(6)、叶盆后缘区域(4)、叶背前缘区域(1)、叶盆叶尖区域(5)和叶背叶尖区域(2)进行激光冲击强化。本发明激光冲击强化方法简单,叶盘激光冲击强化后,残余压应力可达300MPa以上,高频振动疲劳寿命提高约6~30倍以上,工件变形较小。
Other AbstractThe invention discloses a laser shock peening method of a blisk. The method is below: first installing the blisk on a flange at the terminal of a trajectory robot through a fixture; then setting an optical system to a third optical path (9) working state, a first optical path (15) working state, a fourth optical path (10) working state, a second optical path (14) working state, the fourth optical path (10) working state and the second optical path (14) working state in order; and respectively conducting laser shock peening on a blade back trailing edge region (3), a blade basin leading edge region (6), a blade basin trailing edge region (4), a blade back leading edge region (1), a blade basin tip region (5) and a blade back tip region (2) of a blisk blade. The laser shock peening method provided by the invention is simple, and after laser shock peening, the blisk has residual pressure stress reaching above 300 MPa, high frequency vibration fatigue life increased by about 6-30 times, and little deformation of the workpiece.
