弹药洞库内部防殉爆隔爆设计与数值模拟

Study of Anti-Sympathetic Detonation Design and Numerical Simulation in Ammunition Cavity Depot

基于我军现有弹药洞库的结构特点,以某典型弹药洞库为原型,对其内部进行了防殉爆隔爆防护设计,并运用数值计算分析了隔爆防护的隔爆效能。研究表明,所采用复合隔爆装置可以使弹药堆垛上所遭受的峰值压力、振动速度和最大加速度都得到极大降低;在弹药洞库内部实施防殉爆隔爆设计,可以极大地衰减爆炸冲击波峰值压力,减小冲击波对弹药垛的毁伤作用,降低弹药洞库内贮存弹药的殉爆概率,防止库存弹药发生整体殉爆,最大限度地减小发生爆炸时的损失。

Based on structure characteristics of our army ammunition cavity depot and taking the typical ammunition cavity depot as the prototype,the anti-sympathetic detonation explosion protection design was studied and the explosion effect of explosion-proof isolation was analyzed by numerical calculation. The research shows that the anti-sympathetic detonation compound isolation device can make the peak pressure,vibration velocity and acceleration of the ammunition storage be greatly reduced. The explosion proof design in ammunition cavity depot can greatly decrease the peak pressure of shock wave and reduce the ammunition stack damage,and decrease sympathetic detonation probability of storage ammunition and prevent the entirety sympathetic detonation in ammunition cavity depot and minimize the loss when the explosion occurred.
