Rubbing Dynamics of Dual‐Disk Rotor System Supported by Oil Film Bearing
Shock and Vibration, Volume 2025, Issue 1, 2025.As the clearance between the rotor and the casing gradually becomes smaller, the probability of collision and friction increases greatly, the rubbing dynamics of the dual disk‐shaft‐bearing system is studied in this paper. Considering the gyro effect of rotor, a dynamic model of the rotor system under nonlinear oil film force is established; the ...

Music Analysis, Volume 43, Issue 2, Page 247-301, July 2024.ABSTRACT In major‐minor tonality, V implies I, and rising fourths, falling thirds and rising seconds between successive chord roots are more common than falling fourths, rising thirds and falling seconds respectively. Possible explanations involve history (in two‐part medieval counterpoint, harmonic major sixths resolved to octaves – maintained in V–I);

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.

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 ...

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 ...

A Reduced-Order Model for the Vibration Analysis of Mistuned Blade–Disc–Shaft Assembly
Applied Sciences, 2019 An effective reduced-order model is presented in this paper for the vibration analysis of a mistuned blade−disc−shaft assembly considering the flexibility of the shaft and the rotordynamic effects.
