Research On The Damage Effectiveness For Tank With Shooting Gate

Tank is one of the most important and strongest targets on the battlefield.It has important guiding significance for anti-tank operation to evalute damage efficiency of the tank under the first hitting.Therefore,this dissertation studies the following three core problems about the mathematical model of the first round hitting probability and shooting delay time of tank gun under the system with shooting gate,target damage characteristic quantity under hit condition and damage effectiveness model of tank gun.For construction of the mathematical model of the first round hitting probability and shooting delay time of tank gun under the system of shooting gate,on the basis of the assumption that gun control error is ergodic gaussian stationary random process,discretize continuous density function to construct the faster transition probability matrix and the slower transition probability matrix,then use the mean estimate time-varying transfer probability matrix to obtain the shooting delay distribution characteristics and analytic representation of the first round hitting probability.Finally,by processing the actual data,numerical simulation shows that the shooting time is sacrificed to improve the first round hitting probability and shooting gate setting can improve the first round hitting probability.According to the construction of target damage characteristic quantity under hit condition,by investigating the shape size and armor material of a tank,according to the vulnerability,the front,side and rear area armor of the target are divided,and the equivalent target model is established.The damage mechanism of different projectiles(armor-piercing projectile,HEAT and shrapnel)is studied,and the corresponding damage effect model is established.Finally,the damage effects of different projectiles on different areas of the target are obtained by numerical simulation.For construction of damage effectiveness model,study on damage of bottom events,effects of projectile distance and attack angle on damage probability are analyzed,mathematical model of damage probability of tank to armored target is established,finally,the damage ability of projectiles(armor-piercing projectile,HEAT and shrapnel)to armored targets at different distances and attack angles is analyzed by numerical simulation.The results of this dissertation provide theoretical methods for better implementation of anti-tank operations.
