摘　　要：研究典型立方体破片对装甲钢的弹道极限(V_(50))影响规律,对战斗部毁伤元威力评估具有重要意义。通过弹道冲击试验获取了质量为8 g的立方体破片在90°着角时,对10 mm厚616装甲钢的V_(50)。基于数值模拟与试验结果的一致性,研究了着靶姿态对3种典型质量(3 g、5 g、8 g)立方体破片,侵彻装甲钢V_(50)的影响规律。结果表明,立方体破片侵彻装甲钢的V_(50)存在波动区间,立方体破片着靶角度的变化,改变了破片着靶截面比动能,影响了穿靶V_(50)。着靶截面积越大,相应的穿靶V_(50)越大;随着破片质量的增加,V_(50)逐渐减小,且侵彻装甲钢V_(50)对着靶姿态越敏感,V_(50)波动区间变大。The influence law of typical cube fragment on ballistic limit(V_(50))of armor steel was studied,which is of great significance to evaluate the damage element power of warhead.The V_(50) of 10 mm thick 616 armored steel was obtained by ballistic impact test with a mass of 8 g cube fragments at an angle of 90 degrees.Based on the consistency of numerical simulation and test results,the influence law of target attitude on three typical mass(3 g,5 g,8 g)cube fragments and intruding into armored steel V_(50) was studied in depth.It was found that the V_(50) of the cube fragment invaded the armored steel had a fluctuating range,and the cube fragment modified the target angle,which essentially changed the target cross-sectional kinetic energy of the chip,which affected the target V_(50).The larger the target cross-section,the larger the corresponding target V_(50);With the increase of chip quality,V_(50) gradually decreases,and the more insensitive the intrusive armored steel V_(50) is to the target attitude,the smaller the V_(50) fluctuation interval.
