Abstract

Laser cleaning is an advanced cleaning technology which is widely used in the manufacturing industry. Compared with the common planar laser cleaning process, the laser cleaning process of curved surface is difficult to control the completeness and homogeneity of the cleaning layer, which has a great influence on the surface quality and mechanical properties of the cleaned parts. Therefore, a three-dimensional numerical model of the laser cleaning process of the curved surface considering the coordinate system transformation of the heat source is established in this paper to clean the alumina on the surface of the 5754 aluminum alloy. The temperature distribution characteristics for different tangent slopes of the laser cleaning path and the temperature variation with time for different cleaning paths of the laser cleaning process are analyzed. The results show that the proposed method can provide important guiding significance for the practical laser cleaning process of the curved surface.

通过数值模拟分析曲面激光清洗过程的温度分布

激光清洗是一种先进的清洗技术，被广泛应用于制造业。与普通平面激光清洗工艺相比，曲面激光清洗工艺难以控制清洗层的完整性和均匀性，对被清洗零件的表面质量和机械性能影响较大。因此，本文建立了考虑热源坐标系变换的曲面激光清洗过程三维数值模型，对 5754 铝合金表面的氧化铝进行清洗。分析了不同切线斜率的激光清洗路径的温度分布特征，以及激光清洗过程中不同清洗路径的温度随时间的变化情况。结果表明，所提出的方法对曲面激光清洗工艺的实际应用具有重要的指导意义。
