A comparison study of steady-state vibrations with single fractional-order and distributed-order derivatives

Open Physics, 2017
We conduct a detailed study and comparison for the one-degree-of-freedom steady-state vibrations under harmonic driving with a single fractional-order derivative and a distributed-order derivative.

Exciton-phonon scattering and photo-excitation dynamics in J-aggregate microcavities

, 2008
We have developed a model accounting for the photo-excitation dynamics and the photoluminescence of strongly coupled J-aggregate microcavities. Our model is based on a description of the J-aggregate film as a disordered Frenkel exciton system in which ...

Modal analysis of multistage gear systems coupled with gearbox vibrations [PDF]

An analytical procedure to simulate vibrations in gear transmission systems is presented. This procedure couples the dynamics of the rotor-bearing gear system with the vibration in the gear box structure. The model synthesis method is used in solving the

Moving mass problem: Complete solution with the effect of initial conditions

MATEC Web of Conferences, 2018
In this contribution, recently published new semi-analytical solution for the moving mass problem [1] is extended to account for the transient terms that adapt the initial part of the complete solution in a way to match the initial conditions.

Variant of multimodal vibration damping of electroviscoelastic structures by appropriate choice of external electric circuit parameters

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016
In technical applications it takes place the problem of vibration damping in certain regions of the structure, at the location of optical sensors for instance, at any external dynamic excitations with no mass increase and no changes in spectral portrait.

On the Steady State Motion of Electro-Magnetic Vibrator

Transactions of the Japan Society of Mechanical Engineers, 1959
In vibratory machineries electro-magnetic vibrators are frequently used as the source of vibration. These vibrators for practical use are of moving-coil or electro-magnet type and are excited with sinusoidal or half-wave rectified current. In order to investigate the fundamental performance of vibratory machineries, the steady state motion of vibrators
