摘　　要：利用DHR-9401型落锤冲击试验机,结合最小碎裂能方法,研究了中空钢化夹层玻璃的厚度、结构配置对其抗冲击性能的影响,并从冲击力载荷峰值、能量吸收率、应变等方面对影响效应进行评估。实验结果表明:玻璃作为日常生活中的承载结构,其厚度和结构配置对性能有很大影响,在控制试样总厚度相同或不同的前提下,随着冲击层厚度的增加,中空钢化夹层玻璃的抗冲击性能明显提高;在试样总厚度不同的前提下,随着内层玻璃厚度的增加,中空钢化夹层玻璃的承载能力显著提高。In order to study the influence of thickness and structure configuration of hollow tempered laminated glass on its impact resistance,DHR-9401 drop hammer impact testing machine combined with the method of minimum fragmentation energy was used in this experiment,and the impact effect was evaluated from the impact load peak,energy absorption rate and strain.The experimental results show that the glass as a bearing structure in daily life,its thickness and configuration have a great influence on its performance.Under the condition that the total thickness of the sample is the same or different,with the increase of the thickness of the impact layer,the impact resistance of the hollow tempered laminated glass is obviously improved.Under the premise that the total thickness of the sample is different,with the increase of the thickness of the inner glass,the bearing capacity of the hollow tempered laminated glass is improved obviously.
