| 摘 要： | 采用有限元方法数值模拟在连续激光辐照下旋转柱壳温度场的变化和分布情况，并分析了热性能参数对温度场造成的影响，同时还比较分析了不同旋转频率对柱壳温度场分布的影响。结果表明，激光作用下旋转柱壳的温升大大低于静止柱壳的温升, 外表面温度呈现出与旋转频率相符的周期性上升过程,而内表面温升由于热传导的原因在较小频率下才表现出这种周期性，当频率增大到一定值时,内表面温升不出现周期性的台阶而是曲线上升。

| Abstract: | A numerical model is presented to simulate the temperature distribution on the rotational cylindrical shell under laser irradiation. Thermal property parameters varying with temperature and the rotating frequency of the cylindrical shell are included and the effect of the variation of the temperature distribution is studied in this paper. Results show that temperature rise induced by laser decreases largely when cylindrical shell rotates; the temperature of exterior surface rises periodically according to the rotating frequency but the temperature of inner surface only has such property with low frequency because of heat conduction. |
