装药弹丸径向冲击剪切安全性实验研究

Experimental Study on Safety of Radial Impact Shear on Explosive Projectile

对装有炸药的弹丸进行径向冲击载荷剪切实验,测得弹丸壳体剪切断裂瞬间的温度变化、剪切断面形状变化以及弹丸内装填炸药的温度和应力,分析了温度、应力对弹丸装药安全性影响,得出了装药弹丸在剪切速度1 m/s的冲击载荷作用下不会发生燃烧或爆炸,为报废弹药安全、环保地销毁处理提供了一种新的技术手段。

Through the radial impact shear experiments on explosive projectile, the experimental data such as the temperature changes of the projectile shell, the shape changes of the shear section, the projectile charge temperature and stress in the shear fracture moment were obtained. Through analysis of temperature and stress on the effect of projectile charge safety when impact shear, the article drew conclusions that the explosive projectile will not occurring fire or explosion under the shear rate of 1 m/s, and it provides a new method for safety destruction of abandoned ammunition.
