Research On The Underwater Explosive Power Field Of The Mother-child Anti-torpedo Warhead

In the current context of world maritime hegemony,if China wants to achieve the goal of moving from "light blue" to "dark blue",it is inevitable to build a strong navy team.In order to build a strong navy,it needs a strong navy fleet.For ships,the main attack weapon threatening the survival of surface ships is torpedoes,so to speak,the success or failure of torpedo defense directly determines the safety of surface ships.Underwater array explosion has a very high application prospect in the field of hard kill torpedo,so it is necessary to study the propagation law of shock wave of underwater array explosion.Because the mechanism of underwater explosion is complex and the field test cost is high,numerical simulation can be used to study underwater explosion.At present,the research is mainly focused on the dynamic response of a single charge to a certain structure under underwater explosion load,and the research on cluster charge is just starting.In this paper,the field test and AUTODYN numerical simulation software are used to study the explosion force field of underwater array.In this paper,the theoretical model of the formation of the underwater explosion power field of multiple charges is proposed,and the empirical formulas for calculating the power field size are proposed based on the cross-sectional area and the total volume of the power field.Finally,the factors that affect the size of the underwater explosion power field are analyzed through the simulation examples of specific working conditions.According to the Monte Carlo method,the damage probability of att(anti torpedo torpedo)submunition and integral warhead to the target torpedo is calculated.The effects of initiation delay,charge distance and charge quantity on the underwater explosion power field and the effects of initiation delay on the torpedo damage probability of ATT submunition are analyzed.
