Damage Effectiveness Evaluation Of Blasting Torpedo To Large Surface Warship

Large surface warships are the powerful support for the navy to exert its power.Torpedo is one of the most important weapons in modern naval warfare.It is a kind of precise weapon with more advanced tactical and technical performance,complex structure and high cost.It is an important task to evaluate the damage effectiveness of torpedoes to large surface warships and use them efficiently.The purpose of damage effectiveness evaluation of blasting torpedoes for large surface warships is to establish vulnerability model and damage effectiveness evaluation system of blasting torpedoes for typical large surface warships,and to provide technical reference for damage effectiveness evaluation of blasting torpedoes in China.By analyzing the STL text file of large surface ship's three-dimensional model,determining the direction of terminal trajectory line,random sampling drop point in CEP,calculating the coordinates of blast point,calculating the peak value of shock wave of target point,calculating the damage tree,calculating the range of damage probability corresponding to the damage level,the calculation model of damage efficiency evaluation for large surface ship is established,and the large surface ship is developed The comprehensive evaluation software of bottom explosion damage is used to verify the evaluation method of damage effectiveness of blasting torpedoes to large surface warships with a specific case of damage effectiveness evaluation of Arley Burke class destroyers.Two kinds of blasting torpedoes are used to evaluate the damage effectiveness of different attack schemes of the large surface ship,the "Alec Burke" class destroyer.The evaluation results show that the damage effectiveness of the same blasting torpedoes to attack the bottom of the large surface ship is better than to attack the ship's side,the damage effectiveness to attack the midship is better than to attack the stern,the damage effectiveness to attack the stern is better than to attack the bow;when attacking the same position,the damage effectiveness to attack the stern is better than to attack the bow The damage probability of heavy torpedo with large charge is higher than that of light torpedo with small charge;the damage efficiency evaluation method in this paper is used,and the calculation results are consistent with common sense.It is concluded that the damage effectiveness evaluation method in this paper can provide technical reference for the damage effectiveness evaluation of typical large surface warships.
