On the target frequency for harvesting energy from track vibrations due to passing trains
(2019-01-01)
There is an increasing desire to monitor the structural integrity of railway tracks and the supporting ballast and subgrade. Track vibration has been proposed as a potential energy source to power wireless sensors for this ...
Rovibrational spectroscopic constants and fundamental vibrational frequencies for isotopologues of cyclic and bent singlet hc2n isomers

Harvesting energy from the vibration of a passing train using a single-degree-of-freedom oscillator
(2016-01-01)
With the advent of wireless sensors, there has been an increasing amount of research in the area of energy harvesting, particularly from vibration, to power these devices. An interesting application is the possibility of ...
The first frequency of cantilevered bars with geometric effect: a mathematical and experimental evaluation
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2013-11-01)
In engineering, a large number of structures may be modeled as cantilevers. Due to their intrinsic characteristics, some of these structures are sensitive to dynamic actions. Gusts of wind are dynamic excitations for which ...
A solução fundamental na obtenção das frequências naturais e autofunções de um sistema de viga dupla Euler-Bernoulli com camada elástica e força axial
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2022-08-18)
In this work we approach a double Euler-Bernoulli beam system with axial force coupled by
an elastic layer. We performed a matrix formulation for the system of equations and for the
boundary conditions, which allows ...
Avaliação da frequência fundamental de vibração de lajes alveolares
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2023-06-22)
Prestressed hollow core slabs are an important alternative for flooring in prefabricated build-ings, as they overcoming large spans, have low weight and are easily assembled. However, these same advantages can result in ...
Quantum chemical calculations and vibrational spectra of the hydroxytrifluoroborate anion
(Marcel Dekker IncNew YorkEUA, 2003)
Free vibration of single and sandwich laminated composite plates by using a simplified FSDT
(Elsevier, 2015-11)
This paper presents a simplified first order shear deformation theory (FSDT) for laminated composite and sandwich plates. Unlike the existing FSDT, the present one has a novel displacement field which include undetermined ...
On the transmissibilities of nonlinear vibration isolation system
(2016-08-04)
Transmissibility is a key parameter to quantify the effectiveness of a vibration isolation system. Under harmonic excitation, the force transmissibility of a linear vibration isolation system is defined as the ratio between ...
