装药长度对爆炸能量分布影响的研究

Study on the Influence of Charge Length on Explosion Energy Distribution

为了研究不同装药长度的炸药爆炸时能量分布的特点和规律,采用水下爆炸法测试了不同长度的导爆索在水下爆炸时,产生的峰值压力、冲击波衰减时间并计算了不同长度导爆索水下爆炸的比冲击波能、比气泡能和总能量;研究结果表明,不同长度的导爆索在水下爆炸时,装药长度对爆炸能量的分布有一定的影响,比冲击波能和炸药爆炸的总能量先随着装药长度的增加而增大,当导爆索长度为9cm,即长径比为15时,比冲击波能达到最大,随后开始下降。而装药长度对比气泡能的影响不大,基本保持不变。

In order to study the characteristics and laws of energy distribution during explosive explosion of different charge lengths,the underwater explosion method was used to test the peak pressure and shock wave decay time of different lengths of detonating cords during underwater explosion and calculate different length guides.Specific shock wave energy,specific bubble energy and total energy of underwater explosions;The results show that when the detonating cords of different lengths explode underwater,the length of the charge has a certain influence on the distribution of the explosive energy.The total energy of the shock wave energy and the explosive explosion increases first with the increase of the length of the charge.The detonating cord has a length of 9 cm,that is,when the aspect ratio is 15,the shock wave energy reaches the maximum and then begins to decrease.The effect of the length of the charge on the bubble energy is not significant and remains basically unchanged.
