| 摘 要： | 首先基于理论模型，模拟了静止激光源作用在玻璃表面的温度场，并与实验结果对比，验证了模型的正确性。之后，基于此模型研究了运动激光源作用玻璃表面的温度场分布，以及激光功率、扫描速率和光斑半径对温度场的影响。结果表明：温度场随着激光源的移动而变化，形状呈现出带尾巴的彗星状；节点温度随激光功率的增加而增加，随扫描速率的增加而减少，随光斑半径的增加而减少。研究结果为激光切割玻璃的机理研究、更好地控制激光，以及更精确地切割玻璃提供了依据，具有重要意义。 |

| Abstract： | Based on the theoretical model, this paper first simulates the temperature field on the surface of glass heated by static laser source, which is compared with the experiment results to verify the correctness of the model. Then, based on that, it studies the temperature distribution on the surface of glass heated by moving laser source and the influence of laser power, scanning rate and spot radius on that. It turns out that the temperature field changes with movement of laser source, whose shape presents the comet with tail. The node temperature increases with the increase of laser power. However, it decreases with the increase of scanning rate and spot radius. The above research provides the basis for studying the mechanism of laser cutting glass and cutting glass more precisely in practice, which is of great significance. |
