The present disclosure provides a numerical simulation method of pulsed laser paint removal and a use thereof. This method establishes a three-dimensional (3D) temperature field model by ANSYS software to perform a numerical simulation of nanosecond pulsed laser paint removal. A high-speed moving pulsed laser is loaded on a surface of the model in a form of heat flux, and a coordinate system is moved to realize loading on different paths. A special surface mesh screening method is used to realize loading on any surface, and it ensures that laser energy distribution on a material surface is in line with reality. In addition, an element birth/death technology is combined to remove an element that exceeds a threshold, so as to intuitively present the surface morphology after laser paint removal. The present disclosure can realize the prediction of the contour of a paint layer ablated by a pulsed laser.
