摘要
基于VA One平台提出了建筑结构中常见的几种双层墙结构隔声模型的建模方法。用双层墙连接(Double Wall Junction,DWJ)建模方式和通过噪声控制措施(Noise Control Treatment,NCT)方式分别模拟了双层铝板隔声结构,与试验结果对比表明DWJ建模方式精度更高。在建立带搭接的双层混凝土墙结构及带龙骨的轻质双层墙隔声结构时,用到了DWJ、user-defined junction、Autoconnect三种建立连接的方式,带龙骨的轻质双层墙每片墙均模拟为Ribbed Plate子系统,这种模拟方式得到的隔声量计算结果与与测试值无论在趋势还是数值上都非常接近。与经验公式的计算结果相比表明,基于SEA法计算得到的双层墙隔声量在精度上要高于经验公式。
The purpose of this work is to present the numerical evaluation of the sound transmission loss of some double-wall configurations and to compare them to the experimental data found in existing literature. The numerical evaluations were carried out through the commercial software VA One. Two approaches were used to model double aluminum wall. The first technique to model this configuration was based on the double wall junction(DWJ). A fictitious noise control treatment(NCT) was used as the second technique. The DWJ procedure allows a better correlationwith the experimental data than the NCT. In order to model double concrete walls with ties and double-leaf wall with studs, three operations(DWJ, user-defined junction and autoconnect) were carried out in each numerical evaluations. Compared with the experimental data, the agreements were very good. Compared with the results calculated by empirical formula, the results solved by numerical evaluation were more accurate.
