| Abstract: | Laser shock forming is a novel technique that uses laser-induced shock wave to shape sheet metal. In the paper, sheet metal forming caused by multi-laser-shocking is investigated on the bases of experiments of single-laser-shock forming, and overlapped and interval laser shock peening are analyzed through simulating the process of the forming of a sheet metal square can. The results show that the precision of sheet metal forming can be improved if rude peening and fine peening are adopted in sequence during the forming of metal sheet. |
