Flow-Coupled Vibrations of Rotor and Seal

Journal of Vibration and Control, 2005
We study the flow-coupled vibrations of an unbalanced rotor and a floating sealing ring. The rotor is high speed; its operating regimes are above second critical velocity. The ring is subjected to Coulomb friction force, which prevents its motion about the casing. At rotor rotation, the intensive vibrations of rotor and floating ring take place and the

Vibrational coupling in carboxylic acid dimers

The Journal of Chemical Physics, 2005
The vibrational level splitting in the ground electronic state of carboxylic acid dimers mediated by the doubly hydrogen-bonded networks are investigated using pure and mixed dimers of benzoic acid with formic acid as molecular prototypes. Within the 0–2000-cm−1 range, the frequencies for the fundamental and combination vibrations of the two dimers are

Vibrational dynamics of DNA. I. Vibrational basis modes and couplings

The Journal of Chemical Physics, 2006
Carrying out density functional theory calculations of four DNA bases, base derivatives, Watson-Crick (WC) base pairs, and multiple-layer base pair stacks, we studied vibrational dynamics of delocalized modes with frequency ranging from 1400to1800cm−1.

Coupling to Vibrational Mode

2010
A higher degree of complexity is added by including coupling between electrons and local vibrational modes. Here, we begin by considering the theory for electronic transport through molecular quantum dots in which bosonic modes, e.g. vibrations, are present.

Coupling for the vibration-damping transmisson of torques

The Journal of the Acoustical Society of America, 1980
A coupling for the vibration-damping transmission of torques, comprising an inner coupling member, which is provided with a substantially radial flange, and an annular outer coupling member, which surrounds the inner coupling member substantially concentrically.

Rayleigh Quotients for Coupled Free Vibrations

Journal of Sound and Vibration, 1994
Summary: Based upon the general thin shell theory and basic equations in fluid mechanics, three kinds of Rayleigh's quotients for coupled fluid-structure free vibrations are developed for arbitrary tanks fully or partially filled with (i) inviscid, irrotational and incompressible fluid, with the effects of free surface waves neglected, (ii) inviscid ...

On the Suppression of Coupled Liquid/Pipe Vibrations

1996
The vibration of liquid-filled pipe systems can be caused by internal (pressure surges) or external (rotating machinery) sources, or a combination of both. Liquid pulsations can be diminished by devices like an air chamber, whereas pipe vibrations can be reduced by suitable supports.

Vibrational spectra of coupled adsorbed molecules

Physical Review B, 1985
The general theory of coupled molecular dipoles is applied to the vibrational spectra of interacting molecules on surfaces. Both classical and quantum-mechanical analyses are presented for the infrared-absorption spectrum. Asymmetric (Fano-effect) line shapes are derived for coupled molecules that interact with electron-hole pairs or optical phonons in
