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３种空气层厚度７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。
The influence of the structural parameters of a damp tank model on the effects of vibration reduction is studied by model testing.The parameters include three kinds of air layer thickness and seven opening rates under a fixed tip gap.A preliminary understanding of the dynamic behaviour of the structure of the damp tank for ships is obtained.
