This invention belongs to the field of metal processing, specifically a numerical simulation method for laser shock strengthening of complex structural parts with adaptive positioning, including the following steps: (1) establishing a structural model of the part; (2) meshing the structural model of the part; (3) customizing the parameters of the VDLOAD subroutine to generate an array of laser loading positions and impact pressures; (4) establishing dynamic explicit analysis steps and boundary conditions, and using the VDLOAD subroutine to calculate the residual compressive stress field formed on the surface of the part after laser shock.
