Travelling waves in rotational machines
L. Půst, L. Pešek
pages 1065 - 1078, full text

This paper is concerned with vibrations of stationary or rotating disk as a simplified model of real bladed turbine disk. Two types of disks are investigated: perfect rotational disk with the same dynamic properties in all radial directions and imperfect disk having different dynamic properties in two independent modes of vibration. Presented study is first part of theoretical analysis intended as a background for evaluation method used in experimental research of vibrations of bladed disk in real rotational machines or their models.
