Abstract: The estimation of the final vibration amplitude of a turbomachinery bladed disk is of extreme practical importance; it is an essential information for the prediction of the level of high cycle fatigue of the blades and for ...

Abstract: The computation of the final, friction saturated limit cycle oscillation amplitude of an aerodynamically unstable bladeddisk in a realistic configuration is a formidable numerical task. In spite of the large numerical cost ...

Abstract: Abstract. In the forcing of a low-pressure turbine (LPT) bladed disk, the final amplitude of the vibration state that sets in is determined by the dissipation produced by the friction forces at the blade-disk contact ...

Abstract: The dynamic behavior of bladed disks in resonance crossing has been intensively investigated in the community of turbomachinery, addressing the attention to (1) the transient-type response that appear when the resonance ...
