摘要

摘要: 采用自行设计的爆炸实验系统，研究了面内尺寸为300 mm × 300 mm和1 000 mm × 1 000 mm的中空钢化夹层玻璃在爆炸载荷下的动态响应规律，分析了PVB胶层厚度、空气层厚度、炸药量以及爆炸距离对中空钢化夹层玻璃抗爆性能的影响。结果表明：(1) 中空钢化夹层玻璃的抗爆性能随着面内尺寸的增加而增强；(2) 无论是大尺寸还是小尺寸的中空钢化夹层玻璃，随着PVB胶层厚度的增加，结构整体的强度增大，试样的承载能力逐渐增强，随着中间空气层厚度的增加，结构整体的稳定性降低，抗爆能力减弱；(3) 改变炸药量和爆炸距离对中空钢化夹层玻璃的动态响应有很大影响，随着炸药量增加、爆炸距离减小，中空钢化夹层玻璃的破坏程度逐渐增大。

Abstract: In this paper, an independently-designed system for explosion experiment is used to investigate the dynamic response law of hollow tempered laminated glass with plane size of 300 mm × 300 mm and 1000 mm × 1000 mm under explosive load. The influence of layer thickness of PVB glue, thickness of air layer, explosive quantity and explosion distance on the anti-explosive performance of hollow tempered laminated glass is analyzed. The results show that: (1) the anti-blast performance of hollow tempered laminated glass is enhanced with the increasement of the plane size; (2) for both large-size and small-size hollow tempered laminated glass, with increasement of the thickness of the PVB glue layer, both the overall strength of the structure and the load-bearing capacity of the sample increase gradually when the thickness of the intermediate air layer increases, the overall stability of the structure decreases and the anti-explosion ability become weaker; (3) changing the amount of explosives and the explosion distance has a strong influence on the dynamic response of the hollow tempered laminated glass. With the increasement of the explosive amount and the reduction of the explosive distance, the damage degree of the hollow tempered laminated glass increases gradually.
