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.
