摘要
本文以舰船异常噪声振动消除的实例为研究对象,从舰船异常噪声振动的形成,识别方法,控制途径等进行理论探讨和研究。噪声源识别是当今公认的难题之一,本文首次提出"参数法"和"频谱法"识别噪声源,并经实例验证,取得消除舰船异常噪声振动的工程应用效果,今后还将为舰船声隐身发挥更大作用。
In order to elimeating the abnormal noise and vibration of warships, the cause of formation, the identification method, and control approach of abnormal noise and vibration of warships were studied theoretically and experimentally.Noise source identification is one of the difficult problems. In this paper, the "parameter method" and "spectral method" are used to identify the source of noise firstly, and verified by examples. The engineering application effect of eliminating the vibration of the ship's abnormal noise is obtained, and it will also play a greater role in the acoustic stealth of ships in the future.
