穿甲机理的数值研究

NUMERICAL STUDY ON PROJECTILE PENETRATIONMECHANISM

  • 摘要: 为了深入开展穿甲机理的研究,本文对三组穿甲问题——钨弹以1000m/s打钢靶,钢弹以1000m/s打钢靶,钢弹以1000m/s打铝靶,作了数值研究,应用流体弹塑性力学模型,二维不定常欧拉型编码CPG-LTDL code进行计算,计算结果与试验对比符合良好。 对计算结果的分析指出:(1)弹丸侵彻能力不是取决于它的整体动能,而是取决于弹靶接触面上的压力,当靶板参数和弹材固定时,可用弹丸初始面积比动能来标志,(2)铝靶在抗侵彻过程中呈流体性态,高强度铝钣的抗侵彻性能不如普通的A3钢钣,因此应致力于研制具有抗高压、耐高温的新型铝材,而不是单纯追求提高铝材的常规强度。

     

    Abstract: In this paper, the numerical study is carried out for three test problems of projectile penetration; a tungsten projectile impacting on a steel target at 1000 m/s, a steel projectile impacting on a steel target at 1000m/s. and a steel projectile impacting on a. aluminium target at 1000 m/s. The basic equations of compressible fluid and elactic-plastic flow in two dimensions and Eulerian typical CPG-LTDL code are used in the numerical calculation. The results of computation are in good agreement with the exp...
