Equivalent Relationship between Cylindrical Charge and Spherical Charge for Underwater Explosion

School of Mechanical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China

摘要

摘要: 柱型战斗部和球形战斗部作为2种最常规战斗部形式, 其水下爆炸性能是其研究的重点, 目前已存的水下爆炸经验公式皆为球形装药。为研究柱型装药水下爆炸压力场是否也存在类似球形场的经验公式, 文中首先定性分析了作用方位和长径比对柱型装药水下爆炸压力场的影响。通过对比分析柱型装药和等药量球形装药压力场, 求得柱型装药与球形装药远场冲击波关系式方程, 并结合球形装药经验公式, 推导得到柱型装药压力场近似经验公式。仿真试验验证了上述公式的准确性。文中的研究可为优化水下战斗部爆炸性能提供依据。

Abstract: Both cylindrical charge and spherical charge warheads are commonly used, so their underwater explosion performances attract more attention. However, the existing empirical formulas are only for spherical charge. To understand if the underwater explosion pressure field of cylindrical charge can be described by the empirical formulas for spherical charge, This paper qualitatively analyzes the influences of the orientation and the ratio of length to diameter on pressure field of cylinder charge underwater explosion, obtains a relationship expression of far field shock waves of cylinder charge and cycle charge by contrasting the pressure fields of cylindrical charge and same amount of spherical charge, and deduce an approximate empirical formula for cylinder charge by considering the empirical formulas for spherical charge. In addition, simulation is conducted to verify the accuracy of the deduced formula. This research may provide the basis for optimizing explosion performance of underwater warhead.
