Abstract

Compressor rotor wheel vibrations have been investigated using the digital speckle interferometry method. The diametrical mode case study experimentally revealed harmonic distortion of the distribution of the displacement along the circumference. Vibration mode distortion was also registered at one of wheel oscillation modes belonging to the family with the same circumference. It has been experimentally shown that parameter mistuning may not only result in changing the wheel disk vibration modes, but also in that of individual blade vibration modes, which makes the interpretation of rig test results more complicated. The localized modes were revealed at high frequencies of the wheel vibrations, when vibration amplitudes of one or several blades significantly exceed those of the rest.
