| 摘 要： | 船用通风机的性能、噪声和振动是衡量风机好坏的重要指标。性能关系到通风效果,噪声和振动关系到船员身体健康、工作效率和安全性。本文首先对船用通风机从进口到出口进行了整体模拟,并在此基础上对叶轮和蜗壳进行了优化设计,使之合理匹配,从而提高风机性能,并从源头上降低空气动力噪声。实验结果表明,与原型机相比,改进之后的风机在设计工况处噪声值降了5dB。同时,本文还通过减小叶轮的偏心距来进行减振研究,使通风机组的结构噪声比原型机下降2dB。

| Abstract: | The performance,noise and vibration of the marine fan are important indicators to measure whether a fan is good or not. Performance is related to the ventilation effect,noise and vibration are related to the health and work efficiency of the crew,and safety of the submarine. In this paper,the impeller and volute design of the marine fan are optimized on the base of the simulated result of the whole marine fan from fan inlet to outlet,so that it can be reasonably matched,thus improving the fan performance an... |
