摘要
精确制导武器和深钻地武器的运用使洞库发生内爆成为可能,洞库自身的生存能力和库存物资的快速供应保障能力,面临着严峻的挑战。本文以某后方弹药洞库为原型,构建了有限元模型,运用AUTODYN有限差分程序,采用Euler-FCT和流固耦合方法,对弹药洞库发生内爆的毁伤特性进行了数值模拟。分析了弹药洞库内爆冲击波的传播特性,峰值压力变化特性和洞库结构与弹药垛的损伤情况。数值模拟结果对弹药洞库发生内爆的毁伤评估及其防护奠定基础。
It is possible that the earth penetrator detonates in ammunition cavity warehouse along with the development of the precision guidance ammunition.The defense ability of underground project is facing bigger and bigger challenge.A finite element model is founded according to the data of some ammunition cavity warehouses.The blast destroy characteristiss in ammunition cavity warehouse is simulated on AUTODYN by ways of Euler-ECT and flow-solid coupling.The characteristics of blast wave spread and peak pressure in ammunition cavity warehouse and damnification of the ammunition are analyzed.The numerical simulation result forms the base for destroy evaluation and defend of blast in ammunition cavity warehouse.
