Analysis of friction characteristic parameters impact on vibration of couple of blades with friction element

Original language description

Presented work concerns with a sensitivity of a harmonically excited bending vibration of a rotating couple of blades with a friction element with regard to the parameters of the friction characteristic. Either of the blades is discretized by FEM using beam elements and continuously distributed weight is concentrated in nodal points. The friction in central contact points between blade shrouds and the friction element is approximated by a continuous function depending on slip velocities of the shrouds relative to the friction element. Considered friction characteristic respects the micro-slip phase at the very low slip velocities and the macro-slip (full-slip) phase at the higher slip velocities. The values of the friction characteristic parameters areidentified by comparison of the numerical simulations of a transient vibration with experiments used in IT AS CR.
