摘　　要：为了研究弹道极限速度对高强度装甲钢抗弹性能的影响,依据A-B模型将球形破片对高强度装甲钢的侵彻过程分解为三个不同的阶段:初始压缩阶段、惯性压缩阶段和绝热剪切阶段,给出不同阶段的能量损失计算公式,进而推导出弹道极限穿透速度的计算公式,并将其计算值与实验值进行了比较.结果表明,实验数据和模型计算结果的误差在10%以内,证明了其计算公式的正确性.To study the influence of ballist limiting velocities on ballistic behavior of high hardness armor steel,the process of spherical fragment penetrating high hardness armor steel was divided into three phases：initial compress phase,inertial compress phase and adiabatic shear phase,by A-B model.Calculation formula of energy losing is given in different processes.The formula was deduced about limiting velocity of sheet penetration.And the results of calculation were compared with the data of experiments.The results show that the error of the experimental data and the model calculation results is within 10%.The correctness of the calculation formula is verified.
