摘要:
为了揭示高速破片对燃料箱的毁伤机理，采用数值计算的方法研究了单破片、多破片撞击燃料箱所形成的液压水锤效应，计算分析了单枚破片的撞击速度和多枚破片之间的距离对箱体变形的影响。结果表明，单枚破片高速撞击燃料箱时，撞击速度每增大100 m/s，变形高度增加4.3%；当多枚破片以1400 m/s的速度撞击燃料箱时，破片之间的距离越小，箱体的变形量越大；当燃料箱体的变形最大时，破片间距为8.3倍破片直径。
Abstract:
Numerical simulation was employed in the study of hydrodynamic ram formed during the penetration of fuel tank by single or multiple fragments to understand the damage mechanism of fuel tank impacted by highenergy fragments. It was then used to analysis the tank distortion brought in by changes in impacting velocity and the distance between the impacting points. The results show that the distortion height of the fuel tank will increase by 4.3% with the increase of impacting velocity by 100 m/s for single fragment penetration; the distortion of the fuel tank will increase with the decreased distance between the impacting points for multiple fragments penetration at a constant impacting velocity of 1400 m/s and reach to the maximum when the distance between the impacting points is 8.3 times the diameter of fragment.
