摘要
采用模型试验研究的方法，探讨了阻尼舱模型的不同结构参数对阻尼舱减振效果的影响，分析了三种空气层厚度七种开孔率在同一稍隙情形下的阻尼减振效果，得到了有关船舶阻尼舱结构减振性能的初步结果。
Experiments on the model of a ship damp tank are carried out in the paper to study the influence of structure parameters of the model on the effectiveness of its vibration reduction. The influence of three different thicknesses of air layer and seven different opening rates in a fixed tip gap on the vibration reduction are studied. Preliminary vibration reduction performance of the tank is obtained.
