Method for reducing heat accumulation of laser cleaning aircraft skin

The invention provides a method for reducing heat accumulation in laser cleaning of an aircraft skin. The method comprises the steps that S1, the aircraft skin is placed on a three-dimensional mobile numerical control platform; s2, working parameters of a laser and a scanning galvanometer are set according to the type, thickness and surface state of an aircraft skin paint layer and the service environment of an aircraft; s3, the aircraft skin is moved through the three-dimensional mobile numerical control platform, high-energy point laser is output through the laser device, the point laser vertically enters the scanning galvanometer and oscillates into line laser to conduct laser cleaning on the aircraft skin, and a paint layer on the surface of the aircraft skin is completely removed; and S4, monitoring the heat accumulation condition in the aircraft skin in real time by using a scanning electron microscope, a confocal microscope and an EDS energy spectrum analyzer on the three-dimensional ...
