| 摘 要： | 本文根据某船螺旋桨的噪声测量和激振试验结果,描述了螺旋桨鸣音的特点和产生鸣音的机理。 为了预报实桨的鸣音,按照作者提出的模拟条件,在空泡水筒中进行了模型试验。 文中还提出了几种消除鸣音的方法。经实船试验,证明这些方法是有效的。

| Abstract: | Peculiarities and mechanism of propeller singing are described based on results of acoustic measurements and vibration excitation tests of a marine propeller.In order to predict singing of a full scale propeller, model experiments performed with simulation requirements, which are given in this paper, were carried out in cavitation tunnel.Methods for eliminating propeller singing are given on the basis of mechanism of propeller singing. The results of ship trials demonstrate that these methods are effective and can be applied to full scale marine propeller. |
