摘要
实验研究了重复频率脉冲ＹＡＧ激光对金属壳密封装药点火以及由此造成的对结构破坏的机理和模式，得到了金属壳内ＲＤＸ、ＰＥＴＮ炸药热爆炸或热爆燃所需激光作用时间与激光功率密度关系。初步的数值模拟结果表明，炸药热点火所需激光作用时间与激光强度、光斑尺寸有明显的依赖关系。
The ignition of metal enveloped explosive by repetitively rulsed YAG laser and corresponding damaging mechanism and mode of metal/explosive structure are investigated from experiments. The relationship between laser output duration needed by ignition of metal enveloped RDX、PETN explosive and laser intensity is given. Preliminary computational simulation show that the laser output time needed by explosive ignition is obviously dependent on laser intensity and spot size .
