摘要
研究了运动石英玻璃板在CO2激光作用下的热效应,在考虑表面辐射和空气对流的情况下建立了数学模型,采用有限元软件ANSYS进行数值计算,得到了运动情况下石英玻璃的温度分布。比较了激光功率、光斑半径和运动速度对温度分布的影响,得到了温度分布与运动速度和激光参数之间的关系。结果显示石英玻璃板的表面温度随激光功率的增加而增加,随光斑半径、运动速度的增加而减小。
In order to investigate the thermal effect of moving quartz glass heated by CO2 laser, a mathematical model was established as the influence of irradiation and convection was considered. The temperature distribution was obtained using the software ANSYS. The relationships between temperature and velocity and laser parameters （power and radius） were obtained by comparing the temperature distribution for different velocity and laser parameters. The results show that the surface temperature of quartz glass increases when the laser power increases, the laser focus decreases and the speed of the quartz glass decreases.
