摘　　要：运用COMSOL有限元分析法构建理想的双室法模型,研究玻璃厚度、空气层厚度及其耦合对双层中空玻璃隔声性能的影响。结果表明,当玻璃厚度恒为5 mm时,中空玻璃的隔声能力随着空气层厚度的增加而增强;当玻璃组合总厚度为27 mm时,玻璃和空气层厚度向相反方向改变时,在500 Hz以下低频段6+15A+6玻璃组合隔声效果最好,在2 000 Hz~4 000 Hz高频段9+9A+9玻璃组合隔声效果最好,在125 Hz~4 000 Hz全频率段8+11A+8玻璃组合隔声效果最好。改变中空玻璃的玻璃组合可以有效改善其在全频段的隔声性能,不同程度地消除隔声谷以及提高平均隔声量,此研究结论可为隔声窗户的制造提供理论依据。Based on the COMSOL finite element analysis method,an ideal double-room method model is constructed to investigate the effect of different types of insulating glass on sound insulation performance under the coupling effect of air layer and glass thickness.The results show that the sound insulation effect of insulating glass increases with the increase of air layer thickness when the glass thickness is a 5 mm constant.When the total thickness of the glass combination is 27 mm and the thicknesses of the glass and air layer change in the opposite direction,the best sound insulation effect of the glass combination is 6+15A+6 in the low frequency band below 500 Hz,9+9A+9 in the high frequency band from 2 000 Hz to4 000 Hz,and 8+11A+8 in the full frequency band from 125 Hz to 4 000 Hz.Changing the combination of insulating glass can effectively improve the sound insulation performance of the glass in the full frequency band,eliminate the sound insulation valley and increase the average sound insulation.The conclusion of this study can provide a theoretical basis for the manufacture of sound-proof windows.
