Harmonic forced vibrations of two rotating blades with friction element
Original language description
The paper focuses on modelling of harmonic vibration of two rotating blades affected by friction in contact of a rigid body placed in between the blade shroud. Harmonic blade excitation is supposed which is uniformly distributed in blade nodes in circumferential and axial direction. Flexible blades are discretized by FEM using 1D Rayleigh beam elements. After friction forces linearization in contact surfaces between the blade shroud and the friction element, equivalent linearization method is applied. Steady vibrations and orbits of central contact points are investigated in dependence on rotational speed and excitation frequency.
