以某民用燃气涡轮辅助动力装置为对象，研究噪声技术在航空发动机振动分析中的应用。采用课题组自行开发的频谱分析软件，对噪声测试系统获得的包含振动量信息的WAV文件数据进行计算，获得3维频谱图。对这些频谱图进行详细分析，可找出可能存在的激振频率及零件共振频率。将噪声测试获得的振动信息与传统的安装在机匣上的振动传感器的测量数据进行了对比，结果表明噪声测试方法可获得更多有用信息。

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.
