裸装药舱内爆炸压力载荷规律研究

摘要
反舰导弹战斗部舱内爆炸载荷(主要包括冲击波和准静态压力)是引起舰船结构总体毁伤的主要因素,科学认识舱内爆炸载荷特性及其作用规律是舰船抗爆结构设计的重要前提.文中采用MSC.Dytran软件,分析了爆炸冲击波在舰船典型舱室结构内的传播与汇聚规律,以及舱内爆炸准静态压力的幅值特性.研究结果表明,三壁面角隅冲击波峰值(P_3)>两壁面角隅冲击波峰值(P_2)>面几何中心点冲击波峰值(P_1),对于立方体结构,P_2为P_1的3～5倍、P3为P_1的9～12倍,准静态压力幅值与Carlson,Moir等经验公式计算结果符合较好.
The explosion load(mainly including shock wave and quasi-static pressure) in the anti-ship missile warhead is the main factor causing the overall damage to the ship structure. Scientific understanding of the characteristics of explosion load and its action rules is an important premise for the anti-explosion structure design of ships.. In this paper, MSC.Dytran software is used to analyze the propagation and convergence regularity of blast shock wave in the typical cabin structure of ship and the amplitude characteristics of the quasi-static pressure in the cabin explosion. The results show that: three wall corner shock wave peak(P3)> two wall corner shock wave peak(P2)> surface geometric center shock wave peak(P1). For the cubic structure, P2 is about 3 ～ 5 times of P1 and P3 is about 9 ～ 12 times of P1. The quasi-static pressure amplitude is in good agreement with the calculation results of Carlson, Moir and other empirical formulas.
