气泡幕的声透射损失和对水中壳体减振的实验研究

An experimental investigation on sound transmission loss and vibration reduction of a vessel in water due to a bubbly curtain

摘要: 通过不同放气孔径和不同放气压差所形成的气泡幕的透声实验,获得了含气浓度在大范围内变化的气泡幕透声损失与频率关系的实验资料。在气泡幕对浮于水中壳体振动的影响的实验中,得到了气泡幕对壳体振动有明显抑制作用的实验结果。

Abstract: Experimental results of sound trasmission loss in a range of frequency through bubbly curtains were obtained, where the air content was in wide range by means of varying pressure difference and the diameter of the pore of bubble-producing appratus. Vibration reduction of a vessel in water due to bubbly curtain was found.
