Vulnerability Assessment Of A Typical Tank Under The Action Of A Certain Armor-piercing Projectile

In order to assess the vulnerability of typical tank under typical HEAT,the target characteristics and typical HEAT are analyzed,mainly includes:analysis of the composition and function of typical tank system,divides of typical tank damage level,establish of typical tank damage tree,computer describe of typical tank and warhead power calculation.The vulnerability evaluation model of tank under typical HEAT is established,this model is constituted by an intersection model of HEAT and tank,a vulnerability model for tank key components,a calculating model of the tank damage probability caused by damages of key assemblies.The vulnerability of different azimuths of typical tanks is calculated,the result shows that the vulnerable area of K damage level of each surface is the smallest.Tank top surface is more vulnerable,the vulnerable areas of M,F and K damage level were 6.95 m2,2.30 m2 and 3.57 m2,respectively.When HEAT attack tank top,right,left and rear area is likely to cause M damage.attack tanks the front of turret area is easy to cause tank F damage.The vulnerable area of the M,F and K damage level on the left side of the tank is 1.90 m2,1.99 m2 and 1.26 m2,respectively.The vulnerability of both sides are basically the same.The vulnerable areas of the M,F,and K levels in front of the tank are 0.87 m2,0.29 m2 and 0.08 m2,respectively.The vulnerable area of the M,F and K levels in the back of the tank were 2.16 m2,0.32 m2,and 0.12 m2,respectively.The average damage probability of the M damage level(0.41)in the back of the tank is 1.25 times the top surface.The influence of the condition of missile and target intersection on the vulnerability of typical tank is analyzed.When the warhead attack tank from the back,as the pitching angle increases,the vulnerable area of M and K damage level increases.Under the same pitch angle,the vulnerable area of M level damage is the largest.When the warhead attack tank from the right side,the vulnerable area of the tank M damage increases first and then decreases with the increase of the pitch angle.The maximum value(8.49 m2)is reached when the pitch angle is 60 degrees.The vulnerable area of F damage level changed little,the average value was 2.60 m2 and 1.60m2,respectively.When the pitch angle is 0 degrees,the tank vulnerable area changes with the various of attack direction.When the warhead attack tank behind with 45 degrees pitch angle,the average vulnerable area of M damage level(7.20 m2)is about 2.93 times of F damage level.
