针对普通破片对柴油箱的引燃破坏效果较差,为了开发针对油箱类目标的新型弹药,文中建立了含能破片击中油箱油层时,油箱内的油气浓度计算模型,分析破片对柴油箱的引燃效果,并用实验加以验证,研究表明:油箱内的油气浓度随破片速度的提高而降低;破片击中油层时,油箱内的油气浓度高于柴油的引燃极限浓度,油箱不能被引燃,破片对油箱的破坏方式,主要表现为水锤效应对油箱壳体的撕裂。

Considering the common fragment is bad at igniting diesel oil box, in order to develop a new efficient ammunition, in this paper, a math model was set up to calculate the concentration of diesel steam, the ability of fragments igniting diesel oil box was analyzed, and an experiment was did to check it. The results indicate that with the velocity becomes faster, the concentration of diesel becomes lower; When the fragments impacts on the liquid part of the oil box, the concentration of diesel steam is higher than the flammability limits, the oil boxes are not ignited; HYDRAULIC RAM happens in the oil box, and the shell of oil box is destroyed.
