Abstract

In order to study the effects of hollow laser parameters on the sheet metal deformation,the dynamic response process and the deformation law of sheet metal deformation were analyzed with 3003 aluminum alloy sheet shocked under different laser parameters.The results show that,the sheet metal obtain initial velocity by hollow laser shock,the velocity of sheet metal in the spot region gradually reduces and the velocity of sheet metal outside the spot region increases,the movement of the entire plate is driven;compared with the deformation of sheet metal by solid laser shock,the deformation zone is relatively flat and well,the forming performance and the forming limit of sheet metal are improved.The forming law of sheet metal can be obtained by selecting different hollow laser parameters,providing a basis for the study about hollow laser shock forming technique.
