激光对旋转金属壳的加热研究

Laser Thermal Effects on Rotating Metal Shell

实验研究了重复频率脉冲 YAG激光对旋转金属壳的加热效应 ,用与金属壳同步旋转的热电偶以及记录装置测量了金属壳内表面的温升。结果表明 ,激光作用下 ,旋转金属壳的温升大大低于静止金属壳的温升 ;在长时间加热下 ,旋转频率对加热效果影响很小。

Repitatively pulsed YAG laser thermal effect on rotating metal shell is investigated from experiment. The rear surface temperature rise of rotating metal shell is diagnosed and recorded by thermal couple and small recorder which rotate together with metal shell. Results show that temperature rise induced by laser decrease largely when metal shell rotates,rotating frequency has little effects on temperature after a long time heating.Preliminary computational simulation results are accord with experiment results.
