摘要
Abstract
Noise technique was applied to vibration analysis of an aero engine. Spectrum analysis of the noise measurement data in the WAV file was carried out by means of the software developed by the project team. The 3-D spectrum diagrams were obtained and analyzed to find the possible exciting frequencies and components and resonant frequencies. The information obtained by noise measurement was compared with that obtained by traditional vibration sensors. The results indicated that the noise measurement can get more useful information.关键词
