双层墙体的隔声反演

对于隔声要求高的建筑,可以考虑双层墙结构。双层墙结构的隔声量可应用统计能量分析(SEA)进行预测,但具体设计往往是隔声的反演过程,即已知隔声要求来确定双层隔声构造和材料。本文作者应用人工免疫算法建立反演模型,对双层墙结构的各层墙的面密度、厚度、弹性模量和空腔的厚度等参量进行预测,然后,以这些参数决定双层墙隔声结构的材料及构造形式。

Inversed sound insulation prediction to a double-leaf wall

With respect to the high sound insulation requirement within a building,a double-leaf wall structure may be considered to employ.The statistic energy analyses(SEA) can be applied to predict the sound insulation of a specified double-leaf wall.On the other hand,realistic engineering practice is a process of inversed sound insulation prediction,i.e.sound insulation requirement is merely known,the configuration and materials of a structure should be determined through inversed prediction.This paper,thus,adopte...
