Investigation of vibration characteristics for bladed-disks with dry friction nonlinearity
MATEC Web of Conferences, 2018 This paper focuses on the vibration characteristics of the bladed-disk subjected to the dry friction damping under periodic excitation. Firstly, the multi-harmonic equation basing on the frequency-domain analysis is established to predicate the steady ...

Nihon Kikai Gakkai ronbunshu, 2016 Although bladed disks of turbomachinery are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, the deviation of the material ...

On Antiresonance in the Forced Response of Mistuned Bladed Disks
Shock and Vibration, 2003 Mistuning in bladed disks usually increases the forced response of the maximum responding blade leading to shortened component life in turbine engines.

Contribution to the dynamic behaviour of bladed disks [PDF]
Applied and Computational Mechanics, 2007 At this time is dominant to design rotors as assembly of few separated bladed disks. Another type of design ordering is that blade buckle together with a part of shaft creates bladed disk.

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Vibration mode shape extraction of bladed disk
, 2022 This research paper deals with the experimental protocol followed to visualize the vibration mode shape of an aero-engine bladed disk. This study is based on a comparison between the numerical results obtained through Finite element methods (FEM) using ...

Characterization of the Anomalous Vibration Response of an Intentionally Mistuned LPT Rotor
Machines, 2022 The wind tunnel facility at the Centro de Tecnologías Aeronáuticas was used to perform a set of experiments to study the effect of intentional mistuning on the forced response behavior of an aerodynamically unstable low-pressure turbine rotor.
