摘要

为了更好地防御大口径穿甲弹的攻击,提高坦克在战场上的生存能力,采用试验研究和数值计算的方法,研究了一种新型爆炸反应装甲对穿甲弹的干扰。通过对穿甲弹以不同的法线角侵彻靶板装甲进行试验,得出不同入射角情况下的穿深,并对防护系数进行计算。结果表明,新型爆炸反应装甲能够有效地干扰穿甲弹,更易造成穿甲弹弹体的质量损失和飞行姿态的改变,破坏其继续穿入主装甲的能力,从而大大提高了对穿甲弹的防护效果。

Abstract

In order to study aging of PBX under low tensile stress, a new device was designed which can conveniently be used to carry out longterm constant tensile loading. The reliability of device was proved by experiments. The longterm tensile loading experiments under different stress states of PBX based on HMX and TATB were done at normal temperature and 45℃.The effect of different stress level and different temperature environment on PBX was studied. The low stress tensile capacity of mould and isostatic pressing PBX were compared. The results show that this experiment can validly be used to study the tensile capacity of PBX,and aging life of PBX under some temperature and some stress states are obtained.
