摘要

为实现反恐行动中非接触爆炸冲击波破门目标,针对金属防盗门实际条件建立数值仿真模型,重点研究了防盗门在非接触爆炸冲击载荷作用下塑性变形破坏过程及规律。结果表明:相同爆炸冲击载荷作用下,实际转动条件防盗门板塑性变形动力响应时间延长,最大变形量远大于四边固支条件下门板变形量;爆炸中心与防盗门距离过近,门板受爆炸产物和空气冲击波共同作用,只出现局部破坏,不能实现门板整体塑性变形;拟合了防盗门板在非接触爆炸冲击载荷作用下变形量计算式,可为反恐破门弹药设计提供依据。

Abstract

According to the actual scene, a simulation model of burglary resistant safety door subjcted to air non-contact explosions was established, and numerical simulation research on plastic deformation process of burglary resistant safety door under the loading of non-contact explosive air-blast wave carried. The results indicated that under the same loading of air non-contact explosive, plastic deformation process in burglary resistant safety door become longer, and the max plastic deformation was larger. The door would be partly damaged by air-blast wave and explosion production in condition of short distance between the door and the explosion point, and the whole plastic deformation would not be achived. A deformation quantity empirical formula of burglary resistant safety door subjcted to air non-contact explosions was obtained. The research could give some suggestions for the design of counter-terrorist door breaching explosive.
