| 摘 要： | 介绍了在中国船舶科学研究中心大型循环水槽中开展的某散货船模型螺旋桨噪声性能试验,试验结果表明在试验工况下,模型螺旋桨已经产生空化,此时主要为螺旋桨的空化噪声.通过对此散货船螺旋桨空化噪声结果的分析,可以得到:螺旋桨的空化噪声峰值频率在50Hz以下；在空化噪声的峰值频率以上,螺旋桨模型的辐射噪声基本以6dB/Oet下降；在试验工况下,整个频段内螺旋桨的辐射噪声比无空化时高10dB以上.

| Abstract: | An experimental research on a model propeller noise of bulk carrier is carried out in large cavitation channel of China Ship Scientific Research Center and introduced in the paper.In the test condition,propeller cavitation noise is the primary noise source of propeller radiated noise.Based on the analysis of this bulk carrier propeller cavitation noise,some characteristics are obtained.The prominent hump is below 100Hz,which is a typical feature in propeller noise spectra.The propeller noise spectra descend... |
