利用10kg H6炸药包,通过实验和数值计算研究了水雷壳体厚度对水雷性能的影响。炸药采用圆柱形,包在6mm或12mm厚的钢质壳体内。对两个不带外壳的炸药包也进行了点火爆炸。实验用压力传感器的记录显示,壳体厚度对远场峰值压力没有影响,但与没有壳体的炸药包相比,会使冲击波能量增加5％。利用SIN和DYNA2D编码进行的数值模拟计算支持实验结果。对气泡脉动周期的测量表明,带壳体的炸药包的气泡能量比不带壳体的炸药包的气泡能量低9％。
The effect of the thickness of the mine shell on the performance of the mine is studied by experiments and numerical calculations using a 10kg H6 explosive pack. Explosives cylindrical, wrapped in 6mm or 12mm thick steel shell. Two unpacked explosives were also fired explosively. Recordings of experimental pressure transducers showed that the thickness of the shell had no effect on the peak pressure at the far field but increased the energy of the shockwave by 5% compared to the case without the shell. Numerical simulations using SIN and DYNA2D codes support experimental results. Measurement of the bubble pulsation period showed that the bubble energy of the explosive pack with the shell was 9% lower than the bubble energy of the explosive pack without the shell.
