摘　　要：激光抛光技术与传统抛光技术相比,具有非接触式加工、高效率、无污染等特点,其目的是提高加工工件的尺寸精度和几何形状精度,降低材料表面的粗糙度。激光抛光伴随着传热传质、熔池内溶体流动、凝固等物理过程,由于熔池高温及瞬时演变的局限性,以数值模拟技术对熔池内部传热流动行为以及形貌演变进行仿真分析受到了国内外学者的广泛关注。综述了激光抛光机理、激光抛光数值模拟中的热源、金属及非金属(如半导体、陶瓷等)材料抛光研究现状与进展,最后对激光抛光数值模拟的未来发展进行了展望。Compared with traditional polishing technology,laser polishing technology has the characteristics of non-contact processing,high efficiency and no pollution.Its purpose is to improve the dimensional accuracy and geometric shape accuracy of processed workpieces and reduce the roughness of the material surface.Laser polishing is accompanied by physical processes such as heat and mass transfer,melt flow in the molten pool,and solidification.Due to the limitations of high temperature and instantaneous evolution of the molten pool,the numerical simulation technologies to simulate and analyze the heat transfer flow behavior and morphology evolution inside the molten pool have received widespread attention from domestic and foreign scholars.Herein this article reviewed the laser polishing mechanism,heat sources in laser polishing numerical simulation,and the research status and progress of metallic and non-metallic(such as semiconductors,ceramics,etc.)material polishing.At last,the future development of numerical simulation of laser polishing was prospected.
