Abstract :
[en] The determination of the vibration characteristics of rotating engine blades is very important for fatigue failure considerations. One of the most promising techniques for measuring blade vibrations is blade tip-timing. Three vibration analysis methods were used on data obtained from a simple mathematical blade tip-timing simulator. The results from the methods were compared statistically. One of the methods, the Global Autoregressive Instrumental Variables approach produced satisfactory results at realistic noise levels. However, all of the techniques produced biased results under certain circumstances.
