Asymptotic Description of Forced Response Vibration Saturation by Friction Forces
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Flutter Amplitude Saturation by Nonlinear Friction Forces: Reduced Model Verification
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Key Features of the Transient Amplification of Mistuned Systems
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
