| 摘 要： | 为了比较不同类型炸药水下爆炸的声波干扰特性,通过TNT,RS211和RS3-4炸药的水下爆炸实验与测试,从5个方面对比分析了3种炸药水下爆炸的水声特性,即冲击波的衰减特性、冲击波的持续时间、炸药能量特性、声压级及功率谱. 结果表明,炸药水下爆炸可以作为强水声干扰源,但在不同距离上3种炸药的声学特性是不一样的,其干扰性能也不同.

| Abstract: | For the comparison of acoustic properties of different types of charge in underwater explosion,the underwater explosion tests of TNT,RS211 and RS3-4 charges have been carried out.The acoustic characteristics of three charges have been measured and analyzed in five aspects of the shock wave attenuation,duration of shock wave,acoustic pressure levels and the power-ratio spectrum.The results showed that the charge in underwater explosion can be taken as a strong acoustic interference source.The acoustic proper... |
