| 摘 要： | 用有限元方法对３０ＣｒＭｎＳｉＡ合金钢材料受重复频率ＹＡＧ（ＲＰＹＡＧ）激光辐照下，材料前、后表面及内部温度分布进行了二维模拟计算。结果表明。在激光作用下，钢材料的温升随激光脉冲周期振荡逐次上升，这种特性随靶内距激光作用中心距离的增大而不明显。实验记录了一个平均的温升效果，与模拟计算的平均效果符合。

| Abstract: | A two dimension finite element model was assumed to evaluate the transient temperature distribution induced by a gaussian laser beam absorbed in 30CrMnSiA steel. The simulation results showed sample surface temperature was characterized by osilating rise with repetivelylaser pulses, which was different from experiment results due to temperature measurement system's longer response time. |
