Flutter analysis of mistuned bladed disk
Nihon Kikai Gakkai ronbunshu, 2015 Although, in designing blades, it is assumed that all blades on a disk are identical (tuned system), the vibration characteristics of the blade is slightly different due to the manufacturing tolerance, the deviation of the material property, and so on ...

Unsteady Aerodynamic Responses of Mistuned Cascade to Incoming Wakes. Mistuning of Stagger Angle.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991 Unsteady aerodynamic responses of a mistuned cascade subjected to incoming wakes from an upstream cascade are investigated in this study, where the extended Nishiyama-Funazaki method is employed. Numerical calculations are made, focussing on the effects of stagger angle mistuning of the cascade. It is accordingly found that there is some possibility of

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.The nonlinear energy sink (NES) has drawn increasing research attention in recent years. In this study, we investigated a novel disc spring‐based vertical NES device capable of counterbalancing payload gravity and providing a combination of linear and cubic restoring forces.

Investigation of the Influence of Splitter Blades on the Resonance Conditions of Impellers
Applied Sciences, 2019 The conventional resonance conditions are derived based on the conventionally designed impellers without splitter blades. This paper proposes the resonance conditions for impellers under the excitation from the impeller−diffuser interaction with ...

NATURAL FREQUENCIES OF TUNED AND MISTUNED BLADED DISCS ON A SHAFT
TASK Quarterly, 2006 The dynamic behaviour of a rotor consisting of two tuned and mistuned bladed discs on a solid shaft is considered. The effect of the shaft’s flexibility on the dynamic characteristics of the bladed discs and the coupling effects between the shaft and ...

Vibrational Response Analysis of Mistuned Bladed Disk
JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1992 When calculating the resonant response of bladed turbine disks, it has been expedient to assume that all blades on a given disk are identical. This leads to the prediction that all blades experience the same amplitude of displacement and stress when excited by forces harmonically related to the rotor speed.

Modelling and analysis of a high-speed turbine impeller concerning mistuning
MATEC Web of Conferences, 2018 As-manufactured impellers behave significantly different from nominal impellers. There are no identical blades due to geometric and material deviations.
