Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

Displacement and Force Control of a Quarter Car Using a Mixed Mode MR Mount

Shock and Vibration, 2013
In hydraulic hybrid vehicles (HHV), vibration in dual-mode pump/motor units should be isolated from the chassis. A mixed mode magnetorheological (MR) fluid mount was adopted to isolate this vibration and was evaluated in a quarter car model. The MR fluid

VIBRATION TRANSMISSIBILITY IN SYSTEMS WITH NONLINEAR DAMPERS

, 2015
Dampers are used in mechanical systems to isolate them from vibration, mainly to dissipate energy and to lower the amplitude of the system behavior near the resonance frequency.

Synergistic Effects of Phenolic Resin and Polymer Architecture on Crosslink Density and Damping in Poly(Epichlorohydrin‐Co‐Ethylene Oxide‐Co‐Allyl Glycidyl Ether) (GECO) Elastomers

Journal of Polymer Science, Volume 64, Issue 16, Page 3471-3491, 15 August 2026.
Phenolic resin reduces crosslink density and alters the viscoelastic response of GECO elastomers. The magnitude of these changes depends strongly on polymer architecture. Damping performance is governed by the combined effects of network density and molecular structure, not resin content alone, providing a framework for designing advanced vibration ...

Control of Vibration of Transmission Lines

The International Journal of Acoustics and Vibration, 2010
The problem of vibration control of overhead line conductors subjected to laminar transverse wind, which induces stationary vibrations by Karman effect, is important due to the consequences on these structures lifetime and service. We consider the conductor (cable) model as the Euler-Bernoulli beam, fulfilling the authors’ condition that detaches the ...

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, Volume 13, Issue 8, Page 1848-1860, August 2026.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

First‐Principle Analysis of the Structural, Elastic, Electronic, and Optical Properties of Novel AHgF3 (A = K and Fr) Perovskite

Nano Select, Volume 7, Issue 8, August 2026.
The evaluation of the physical properties of novel KHgF3 and FrHgF3 perovskites is explored. Both compounds are thermodynamically stable and mechanically ductile. Featuring narrow band gaps around 0.53–0.60 eV, these materials show strong potential for use in flexible infrared‐to‐visible optoelectronics and energy conversion devices.

Vibration and Galloping of Transmission Lines [PDF]

The Journal of the Acoustical Society of America, 1968
Aerodynamically excited vibrations of overhead conductors impose serious economic and operational difficulties on heavy-duty transmission lines. The various types of vibration that are of engineering significance, field observations, and methods of study and of controlling these problems will be reviewed.
