某型加弹丸爆炸破片设防安全距离研究

Study on Fortification Safety Distance Preventing Fragment of Certain Cannon Fragmentation Projectile Blasting

以人员为防护目标,分析利用危险破片密度概念计算破片设防安全距离的可行性并推导计算公式。通过对无保护情况下人员被杀伤概率的计算,认为以美军的危险破片密度标准计算破片设防安全距离,人员的风险率过大;而以出现人员死亡事故的概率为百万分之一作为安全准则,计算出某型加弹丸爆炸的破片设防安全距离为444m,且在该距离上的危险破片数为2块。

Taking personnel as protective target, analyze the feasibility that using the conception of hazardous fragments density to calculate the fortification safety distance preventing fragment and derive its formula. By means of accounting the kill probability of unprotected personnel, conclude that the risk of personnel is too high when using the conception of hazardous fragments density in American Military Standard to calculate the safety distance; and taking micro kill probability of unprotected personnel as safety criterion, this paper has calculated the fortification safety distance preventing fragment of certain cannon fragmentation projectile blasting which is 444 meter, and the quantity of hazardous fragments at this distance is 2.
