Mode family identification of a blisk by tip timing measurements

Résumé

The study consists in tip timing measurements to identify a mode belonging to a certain family (flexural, torsional, etc). It can be performed placing different probes over blade tip profile and, thus, relating its deformed state with a mode family. The identification is performed for modes generating either standing or travelling wave response. It is followed by amplitude and phase distribution calculation of each blade for identification of nodal diameters number. Additionally a frequency response is obtained in order to calculate modal damping ratio.
