摘　　要：利用LS-DYNA有限元软件,基于多物质ALE算法,模拟中空夹层玻璃在爆炸载荷下的动力学响应,通过变化PVB夹层属性和中空气体层厚度分析了其改变对玻璃板板心最大挠度的影响。结果表明:(1)随气体层厚度的增加,中空钢化夹层玻璃上层玻璃板挠度减小而下层玻璃板挠度增加;(2)一定气体层厚度下,随夹层杨氏模量的增加,上、下玻璃板的挠度减小。This paper simulated the dynamic responses of hollow tempered laminated glass under the blast load based on a multi-material ALE algorithm using the software LS-DYNA,and analyzed the effect of changing the PVB interlayer property and the thickness of the hollow gas layer on the maximum deflection of the glass plate.The result shows that,with the increase of the thickness of the gas layer,the upper glass plate deflection of the hollow laminated glass decreases,while the lower glass plate deflection increases. However,the deflection of the upper and lower glass plates decreases with the increase of the Young's modulus of the interlayer. The results provide a reference for the safe and efficient design of the hollow laminated glass.
