摘要

摘要: 为研究爆炸冲击波对钢化玻璃的毁伤阈值，开展了钢化玻璃冲击波毁伤效应实验。对每一发实验进行了爆炸参数测试，获得了冲击波超压随时间变化历程的实验数据。通过对实验数据的处理与分析，得到了爆炸冲击波基本参数，包括正反射超压、冲击波到时、正压作用时间、正反射冲量、负反射超压、负压作用时间和负反射冲量等。将实验结果与CONWEP计算结果进行了比较，比较结果表明二者误差很小，证明冲击波测试结果准确可靠。对冲击波正负反射参数进行了比较，结果表明冲击波正反射参数明显高于冲击波负反射参数。

Abstract: Damaging effects of blast waves on tempered glasses were experimentally investigated to explore the blast damage threshold of the tempered glasses. The blast shock wave parameters were tested in each experiment, and the experimental overpressure-time histories were obtained. By analyzing the experimental data, the blast shock wave parameters were obtained, such as normally reflected overpressure, arrival time of the shock wave, duration of the normally reflected overpressure, normally reflected impulse, negative reflected overpressure, duration of the negative reflected overpressure, and negative reflected impulse. Compared with the results computed by the CONWEP program, the relative errors were small, which verified that the tested results were accurate and reliable. Meanwhile, the normally reflected parameters are greater than the corresponding negative reflected ones.
