On the attenuation of vibration using a finite periodic array of rods comprised of either symmetric or asymmetric cells
(2021-10-27)
Periodic structures have an important role to play in the reduction of vibration within a targeted frequency range. Much of the literature concerning vibrations in periodic structures involves the description of wave ...
The Characteristics of Vibration Isolation System with Damping and Stiffness Geometrically Nonlinear
(2016-10-03)
The paper concerns an investigation into the use of both stiffness and damping nonlinearity in the vibration isolator to improve its effectiveness. The nonlinear damping and nonlinear stiffness are both achieved by horizontal ...
Análise dinâmica de amortecedores tipo stockbridge
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2014-05-08)
Overhead transmission lines of electric power are submitted to the action of winds, which in turn promote wind over the wire cable vibrations. These vibrations cause damage due to fatigue by bending and by abrasion on the ...
Online Sequential Extreme Learning Machine for Vibration-Based Damage Assessment Using Transmissibility Data
(ASCE-Amer Soc Civil Engineers, 2016)
Traditional vibration-based damage assessment approaches include the use of feed-forward neural networks. However, the slow learning speed of these networks and the large number of parameters that need to be tuned have ...
Predicting the stop-band behaviour of finite mono-coupled periodic structures from the transmissibility of a single element
(2021-06-01)
The study of mono-coupled periodic structures has gained renewed interest by the scientific community due to the new applications of metamaterials and meta-structures. Much research has focused on the wave propagation ...
An investigation of a two-stage nonlinear vibration isolation system
(2013-03-18)
This paper investigates the most desirable configuration of a two-stage nonlinear vibration isolation system, in which the isolators contain hardening geometric stiffness nonlinearity and linear viscous damping. The force ...
