摘要：研究常規(guī)彈藥爆炸后破片和沖擊波的作用規(guī)律.通過(guò)對(duì)彈片和沖擊波運(yùn)動(dòng)規(guī)律的分析認(rèn)為,按照以往的模型進(jìn)行計(jì)算時(shí),存在TNT當(dāng)量不守恒的問(wèn)題.研究了TNT當(dāng)量守恒條件下,沖擊波和破片同時(shí)到達(dá)目標(biāo)距離的問(wèn)題,所得計(jì)算模型較以往的模型更為合理.對(duì)于mpmax,沖擊波和破片同時(shí)到達(dá)的距離為4.26m,以往模型為3.76 m;對(duì)于mp,沖擊波和破片同時(shí)到達(dá)的距離為4.30m,而以往模型為3.83 m,偏差約13％.另外,經(jīng)過(guò)理論推導(dǎo)和計(jì)算認(rèn)為,沖擊波和破片同時(shí)到達(dá)目標(biāo)的距離,與破片形狀和破片質(zhì)量關(guān)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 m-p,the distance is 4.30 m,and the traditional model is 3.83 re,the aberration is about 13%. In addition,it gets the distance on which fragment and shock wave reaches on the same time has little relation-ship to the shape and mass of fragment through the theoretical calculation.
