不同装药的水下爆炸冲击波特性研究

Study on Shock Wave Characteristics of Different Charges by Underwater Explosion

摘要: 通过对复合PBX、熔梯黑铝、热塑梯黑铝和TNT等4种炸药在无限水域中的水下爆炸试验和测试，分析了4种炸药水下爆炸时的冲击波峰值压力、时间衰减常数和冲击波冲量等特性参数，评估了4种炸药的水下爆炸冲击波性能.结果表明：4种装药的冲击波峰值压力从高到低分别是热塑梯黑铝、熔梯黑铝、TNT、复合PBX；时间衰减参数从高到低分别是复合PBX、热塑梯黑铝、熔梯黑铝、TNT；冲击波冲量从高到低分别是复合PBX、熔梯黑铝、热塑梯黑铝、TNT.因而，综合各参数评估，认为复合PBX是几种炸药中性能最好的，熔梯黑铝和热塑梯黑铝比较接近，TNT则最差.

Abstract: Characteristic parameters, such as impact wave pressure, time reduces constant, etc, of complex-PBX, fusing THL, thermoplastic THL and TNT are analyzed utilizing tested data in underwater explosion. Underwater explosion power of different charges is compared. The result indicates that the peak pressure of four charges are, from high to low, thermoplastic THL, fusing THL, TNT, complex-PBX; Decay constant are, from high to low, complex-PBX, thermoplastic THL, fusing THL, TNT; Contrast shock wave pressure impulse are, from high to low, complex-PBX, fusing THL, thermoplastic THL, TNT. Therefore, complex-PBX is the best performance of charges by multi-parameter comprehensive evaluation.
