Effectiveness of Straight‐Wall and Sloped‐Wall House Hold Water Tank Acting as a Tuned Liquid Damper in Mitigating Structural Vibrations: A Dynamic Assessment

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This research distinguishes the performance of three types of water tanks, which are acting as tuned liquid dampers (TLDs; i.e., rectangular shape flat‐bottom with straight wall, square shape flat‐bottom with straight‐wall, and square shape flat‐bottom with sloped‐wall tanks) in the same plan area firmly fixed to the upper most part of the G+7 framed ...

An Innovative Semiactive Rolling Tuned Mass Damper for Structural Vibration Mitigation

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
This study introduces a novel semiactive rolling tuned mass damper (SARTMD) developed to mitigate structural vibrations more efficiently than conventional tuned mass dampers (TMDs), with a primary objective of significantly reducing absorber mass without compromising performance.

Study on the Load‐Adaptive Control Method of Quasizero Stiffness Vibration Isolator Based on the Semi‐Analytical Solution

Shock and Vibration, Volume 2025, Issue 1, 2025.
For the quasizero stiffness (QZS) isolators, the mismatch between the stiffness and the load will significantly impact the vibration isolation performance, greatly reducing the isolation efficiency and complicating the load motion. Therefore, a load‐adaptive method is designed innovatively based on a semianalytical solution of the QZS isolator, which ...

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 ...

The Origin of the Dominant: Schoenberg's ‘Strong Progression’ and the Realisation of Implied Virtual Pitches

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);

Analytical Solution and Energy Flow Analysis of a Vertical Vibration‐Controlled System Using the Nonlinear Energy Sink

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.

Study on vibration response characteristics of mistuned bladed disk (Mistuning phenomena evaluated by vibratory stress)

Transactions of the JSME (in Japanese), 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 property, the wear during operation, and so on.

Research on vibration localization of mistuned bladed disk system [PDF]

Journal of Vibroengineering, 2017
In order to assess the vibration localization influences of different parameters of structural of the mistuned bladed disk system, the pre-stressed component mode synthesis method was adopted, and reduced-order models (ROMs) of the aero-engine compressor bladed disk system were built.

Study on vibration characteristics of mistuned bladed disk (Effect of bladed disk structure on mistuning characteristics)

Transactions of the JSME (in Japanese), 2019
Although bladed disks are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all the blades on a disk are slightly different due to the manufacturing tolerance, deviations in the material properties, and wear during operation. These small variations break the cyclic symmetry.

Effects of Crack on Vibration Characteristics of Mistuned Rotated Blades [PDF]

Shock and Vibration, 2017
Rotated blades are key mechanical components in turbine and high cycle fatigues often induce blade cracks. Meanwhile, mistuning is inevitable in rotated blades, which often makes it much difficult to detect cracks. In order to solve this problem, it is important and necessary to study effects of crack on vibration characteristics of mistuned rotated ...
