摘　　要：榴弹作为打击空中目标的弹种之一,其破片与冲击波威力是评价毁伤能力的重要一环。参考意大利奥托·梅莱拉127 mm榴弹,设计榴弹模拟弹,分析其综合威力。采用实验、数值仿真与经验公式相结合的方法,分析破片速度、破片空间分布规律和冲击波超压。实验结果表明,榴弹模拟弹飞散方向角为93.67°,飞散角为65.42°,破片初速为1451 m/s。仿真和计算结果表明,飞散角的理论计算值与实验值相对差较小;破片速度理论值与实验值相对差不超过20%;冲击波超压理论值、仿真值与实验值相对差不超过15%。As one of the main ammunitions for attacking air targets,the fragmentation and shock wave power of grenades are important parts of evaluating damage ability.In order to study the comprehensive power of grenade,grenade simulation ammunition is designed refers to Italy s Oto Melera 127 mm ammunition.On the basis of experiment,numerical simulation and empirical formula,the fragmentation velocity,fragmentation spatial distribution and shock wave overpressure are analyzed.The experimental results show that,the scattering direction angle of the grenade simulation ammunition is 93.67°,the scattering angle is 65.42°,and the initial velocity of the fragments is 1451 m/s.The simulation and calculation results show that,for the scattering angle,the deviation between theoretical and experimental values is relatively small,for fragmentation velocity,the error between theoretical calculation and experimental value is less than 20%,for shock wave overpressure,the error of theoretical value,simulation value and experimental value is less than 15%.
