摘要
该文分析汽轮机组噪声及其频谱是如何产生的．以２００ＭＷ汽轮机为例，对其噪声及频谱是如何产生的作了较详细地分析计算．笔者做了动静摩擦故障与噪声的模拟试验，并探讨利用噪声传性进行汽轮机故障诊断．图３表１参８．
Abstract The paper discusses how steam turbine noise and its spectrum are generated.Taking a 200 MW steam turbine as an example,a detailed anlytical calculation concerning the formation of its noise and its spectrum is presented. The author has performed some experiments on noise with simulated rubbing accidents between rotating and stationary parts and has explored the psssibility of utilizing noise particularities for steam turbine failure diagnosis.
