摘要

摘要: 为了研究壳体厚度和材料对水声干扰子弹威力的影响, 在Cole水下爆炸冲击波经验公式的基础上, 利用AUTODYN仿真程序对水声干扰子弹水下爆炸进行模拟, 分析了子弹壳体厚度和材料对水下爆炸声压级的影响, 仿真结果表明, 水下爆炸声压级随着壳体厚度的增加先升高后降低; 壳体材料的屈服应力越大, 水下爆炸声压级越高。仿真结果为工程应用提供理论参考。

Abstract: To study the effects of shell thickness and material on power of underwater acoustic interfere munitions by AUTODYN software, based on the Cole′s underwater explosion empirical formula, the sound pressure level of shock wave created by underwater explosion of TNT with a metal shell is calculated for different thickness and material of the shell. Rela-tions among the sound pressure level of shock wave, the shell thickness and the shell material are analyzed. Simulation results show that the sound pressure level of shock wave increases first and then decreases with the thickness; and the higher the yield stress of shell material, the higher the sound pressure level of shock wave.
