【摘要】 采取对中置薄玻璃开气压平衡孔的方法优化薄玻璃在风荷载作用下的受力状态，并利用有限元分析手段，研究气压平衡孔对窄腔室薄型中空玻璃位移、应力以及腔室厚度的影响规律。结果表明：直径1 mm的气压平衡孔可减小风荷载作用下窄腔室薄型中空玻璃中片玻璃的最大位移与板心最大主应力，且减小量随风荷载增大而增大。随中片玻璃厚度减小，中片最大位移减小量先减小后增大，板心最大主应力逐渐减小。随外、内片玻璃厚度减小，中片玻璃最大位移与板心最大主应力减小量均逐渐增大。当外、内片玻璃厚度较薄，中片玻璃较厚时，在5 kPa高风荷载下外、中片玻璃会与板心区域发生接触，从而导致中片玻璃在接触位置产生应力集中。更多还原

【Abstract】 This study proposes the implementation of air pressure balance hole in the intermediate thin glass layer to optimize its mechanical behavior under wind loads. Finite element analysis was employed to investigate the influence patterns of these pressure balance holes on the displacement,stress,and cavity thickness variations in thin-chamber insulating glazing(TC-IG). The results indicate that 1 mm diameter pressure balance holes effectively reduce both the maximum displacement of the middle glass and the principal stress at glass center under wind loads,with the reduction magnitude increasing proportionally to wind load intensity. As the thickness of the middle glass decreases,the displacement reduction initially diminishes then increases,while the principal stress reduction shows gradual enhancement. Thinning of both outer and inner glass leads to progressive increases in displacement and principal stress reductions of the intermediate layer. Notably,under high wind load conditions of 5 kPa,contact phenomena occur between outer and middle glass when the outer and inner glass are relatively thin compared to the middle glass,resulting in stress concentration at the contact position near the panel center.更多还原
