摘要
近年来,负压风机在船舶通风、散热、换气等方面发挥着重要作用。目前,负压风机存在噪声高、工作效率低等问题,如何降低风机噪音成为人们研究的重点。本文研究负压风机噪声产生的原因,在此基础上,利用形貌优化算法对船用负压风机进行降噪设计,降低风机工作的噪音,满足船舶对风机性能的需求。
In recent years, the negative pressure fan plays an important role in the ship ventilation, heat dissipation, and ventilation. At present, there are many problems such as high noise and low working efficiency, how to reduce the noise of the fan becomes the focus of the study. This paper studies the causes of the negative pressure fan noise, and reduced the noise of the negative pressure fan by using morphology optimization algorithm.
