摘要
研究常规弹药爆炸后破片和冲击波的作用规律。通过对弹片和冲击波运动规律的分析认为,按照以往的模型进行计算时,存在TNT当量不守恒的问题。研究了TNT当量守恒条件下,冲击波和破片同时到达目标距离的问题,所得计算模型较以往的模型更为合理。对于mpmax,冲击波和破片同时到达的距离为4.26 m,以往模型为3.76 m;对于mp,冲击波和破片同时到达的距离为4.30 m,而以往模型为3.83 m,偏差约13%。另外,经过理论推导和计算认为,冲击波和破片同时到达目标的距离,与破片形状和破片质量关系不大。
The action law of fragment and shock wave of traditional ammunition explosion was studies.Through analyzing the action law of fragment and shock wave,it thinks that the traditional model is not suitable because the total TNT is not conservation.So this paper studies the distance on which fragment and shock wave reaches on the same time under the condition of the TNT is a conservation,which is proved to be more suitable to the traditional model.For mp max,the distance on which the fragment and shock wave reaches is 4.26 m,and the traditional model is 3.76 m;meanwhile,for mp,the distance is 4.30 m,and the traditional model is 3.83 m,the aberration is about 13%.In addition,it gets the distance on which fragment and shock wave reaches on the same time has little relationship to the shape and mass of fragment through the theoretical calculation.
