Damage Effectiveness Evaluation Of Blasting Torpedo On Submarine

In marine warfare,submarines,as the main underwater attack weapon platform,have strong attack ability.The submarine can be effectively destroyed in combat,which can greatly weaken the enemy ’ s underwater combat force and affect the whole combat process.Aiming at the related problems of submarine damage efficiency evaluation,this thesis studies the damage efficiency evaluation of blasting torpedo on submarine,analyzes the vulnerability of submarine targets,calculates the damage power data of blasting torpedo,develops the damage efficiency evaluation module and realizes the damage efficiency evaluation of submarine under different schemes,which provides technical support for submarine damage efficiency evaluation.In this thesis,based on the research status of submarine target vulnerability,underwater explosion of explosive torpedo and submarine damage effectiveness evaluation at home and abroad,taking ’ Los Angeles ’ nuclear submarine as the research object,based on the research method of target vulnerability,the structure and function characteristics of the submarine are analyzed,and the three-dimensional model of the submarine target is established.The damage tree of the submarine system is constructed,and the damage level is divided.The 0-1 function damage law of the submarine component and the peak damage criterion of the shock wave are set.The vulnerability model of the ’Los Angeles’ nuclear submarine is constructed by combining the STL file of the submarine model with the vulnerability information.In order to calculate the power field data of explosive torpedo,three different types of explosive torpedo were selected as the research object.The damage effect of torpedo warhead explosion in water was analyzed.The main damage elements were determined as shock wave and bubble in water.The peak value of shock wave and the maximum radius of bubble were calculated respectively,which provided the corresponding damage data for the damage model of torpedo warhead.In order to study the damage effect of underwater detonation wave on submarine cabin,based on numerical simulation method,the process of different torpedo warheads damaging different cabins of submarine is simulated,and the damage effect of cabin is analyzed,which provides theoretical reference for submarine damage efficiency evaluation.In order to solve the problem of submarine damage efficiency evaluation,this thesis uses Qt Creator to build the damage efficiency evaluation platform of submarine,sets the relevant missile-target rendezvous parameters,establishes the damage efficiency evaluation scheme of different torpedo attacking different parts of submarine,and evaluates the damage efficiency.The evaluation results show that the strike effect of the upper part of the midship command platform of the torpedo damage vessel is the best for different parts of the submarine.The damage probability of the three types of torpedoes reaches more than 90 %,and the damage level reaches grade I.The damage probability of heavy torpedoes reaches 97.51%,medium torpedoes 94.94%,and light torpedoes 91.18%.
