摘要
采用模型试验结合数据回归的方法对螺旋桨空泡噪声进行预报。首先采用两种不同的回归方法对空泡噪声进行预报,然后同大型循环水槽模型试验结果进行比较,对结果进行分析,得到两种回归方法的使用范围。同时,也验证了这一航速对螺旋桨空泡噪声的影响规律。
The propeller cavitation noise in frequency-domain was predicted by using the regression method and doing model experiments.First,two regression methods were used to calculate the cavitation noise.Those calculated results were compared with the experimental date which was gained from the experiments in a large circling channel.The range of using these two regression methods was gained through analyzing three results.Meanwhile,the influence of different sailing speeds of a ship on its propeller cavitation noise was tested.The conclusion is that the propeller cavitation noise increases with the ship speading up.
