摘要

摘要: 为了提高鱼雷水下近场爆炸对潜艇的毁伤效果, 分析爆炸载荷作用下潜艇结构鞭状运动响应规律,文中从能量叠加关系出发, 将爆炸载荷按时间顺序分解为冲击波载荷、气泡脉动载荷和气泡低压载荷3个阶段。建立单质点弹簧系统, 分析三阶段载荷与潜艇结构振动之间的能量叠加关系, 并基于对载荷的分析, 对不同能量结构的潜艇结构鞭状运动响应进行仿真。仿真结果与试验数据吻合较好, 说明单质点弹簧系统能够定性描述鱼雷在潜艇中部近水场爆炸时, 潜艇结构鞭状运动的能量叠加关系。文中工作可为分析鱼雷近场水下爆炸载荷作用下的潜艇结构鞭状运动毁伤效果提供理论依据。

Abstract: To improve the damaging effect of a near-field underwater explosion caused by a torpedo on a submarine, the whipping response law of a submarine structure under an explosive load is analyzed. In this study, based on the energy superposition relationship, the explosive load can be divided into three stages: shock wave stage load, bubble pulsating load, and bubble low-pressure load; these can be arranged according to the explosive levels. The particle-spring system is established to analyze the energy superposition between each load stage and submarine structure vibrations. The submarine whipping response based on different energy constructions is simulated based on load disassembly. The simulation results are in good agreement with the sea trial data, indicating that the particle-spring system has significant advantages in a qualitative analysis of the submarine energy superposition owing to the torpedo near-field underwater explosives. The proposed method can be used as a theoretical reference for analyzing the damaging effect of a submarine structure whipping response of near-field underwater explosions caused by a torpedo
