Forced Transverse Vibration of a Closed Double Single-Walled Carbon Nanotube System Containing a Fluid with Effect of Compressive Axial Load

Shock and Vibration, 2015
Based on the Rayleigh beam theory, the forced transverse vibrations of a closed double single-walled carbon nanotube (SWCNT) system containing a fluid with a Pasternak layer in-between are investigated.

Some relevant aspects of footbridge vibrations [PDF]

Facta Universitatis. Series: Architecture and Civil Engineering, 2002
Considering the contemporary structural inaterials that are becoming more resistant, having higher strength to weight ratio, and the fact that live load of footbridges is low, the design based on static analysis only, respecting ultimate limit states ...

FORCED VIBRATION ANALYSIS OF A MULTIDEGREE IMPACT VIBRATOR

Journal of Sound and Vibration, 1998
The dynamics of a multidegree impact vibrator subject to harmonic loading is investigated. The system is represented by a lumped mass model which hits and rebounds from a rigid wall during vibration. The periodic solution to the equations of motion with $N$ forcing cycles and $P$ impacts is formulated.

Relaxation of a qubit measured by a driven Duffing oscillator

, 2010
We investigate the relaxation of a superconducting qubit for the case when its detector, the Josephson bifurcation amplifier, remains latched in one of its two (meta)stable states of forced vibrations.

Free and Forced Vibrations of Periodic Multispan Beams

Shock and Vibration, 1994
In this study, the following two topics are considered for uniform multispan beams of both finite and infinite lengths with rigid transversal and elastic rotational constraints at each support: (a) free vibration and the associated frequencies and mode ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

The Influence of the Shaft Mass on the Natural Pulsation of the Free and Forced Transverse Vibrations and Having a Homogeneous Wheel Mounted at the End

Scientific Bulletin of Valahia University: Materials and Mechanics
The paper aims to study the influence of the mass of the shafts on the natural pulsations of the free and forced transverse vibrations of an elastic system formed by a fixed shaft and a homogeneous wheel for two cases: free vibrations and forced ...

Rotor vibration caused by external excitation and rub [PDF]

, 1982
For turbomachinery with low natural frequencies, considerations have been recently required for rotor vibrations caused by external forces except unbalance one, such as foundation motion, seismic wave, rub and so forth.

Lock-in of the vortex-induced vibrations of a long tensioned beam in shear flow [PDF]

, 2011
The occurrence of lock-in, defined as the local synchronization between the vortex shedding frequency and the cross-flow structural vibration frequency, is investigated in the case of a tensioned beam of length to diameter ratio 200, free to move in both
