摘要

摘要: 为研究多发爆炸荷载作用下方钢管构件的动态响应及损伤情况，依据方钢管单发爆炸试验确定合理的模型参数，分析了近场爆炸总药量相同的条件下药量等分份数、药量质量比以及起爆时间间隔3种因素对方钢管构件抗爆性能的影响。结果表明：多发等分药量同时起爆时，方钢管迎爆面变形和挠度分别比单发爆炸时大17.5%和32.1%；对于两发爆炸荷载，当两发炸药的质量接近时，方钢管迎爆面变形和挠度比质量差异较大时大18.3%和19.7%。对于多发等分药量爆炸荷载：当各炸药爆心到方钢管跨中的距离相同时，非同时起爆时方钢管迎爆面的变形比同时起爆时小4.3%，且起爆时间间隔越长，变形越小；当各炸药爆心到方钢管跨中距离不同时，调整各炸药起爆时间可使方钢管迎爆面跨中变形比同时起爆时大13.9%。

Abstract: In order to study the dynamic response and damage of square steel tubular structural components under near-field multiple blast loads, the explosion resistance performance of square steel tubes is obtained from the number of equal parts, the charge mass ratio and the initiation time interval at the same total explosive charge based on the explosion test. The results show that when the total explosive is equally divided with simultaneous detonation, the deformation on the front surface and the deflection of the tube under multiple blast loads are both larger than that of the tube under single blast load by 17.5% and 32.1%, respectively. For two explosive loads, when the mass of the two explosives is close, the deformations on the front surface and the deflection are greater than that the mass of the two explosives is quite different by 18.3% and 19.7%, respectively. For multiple blast loads, when the distance between the explosive center of each explosive and the mid-span of the tube is equal, the deformation on the front surface of the tube with non-simultaneous detonation is smaller than that of the tube with simultaneous detonation by 4.3%, and the longer the initiation time interval is, the smaller the deformation will be. When the distance between the explosive center of each explosive and the mid-span of the tube is not equal, if the initiation time of the explosives is appropriate, the deformation on the front surface of the tube with non-simultaneous detonation can be larger than that of the tube with simultaneous detonation by 13.9%.
