Dynamic response and Vibration
-
The paper "Dynamic response analysis of nanobeams resting on elastic foundations" uses the finite element method to study the dynamic response of nanobeams resting on an elastic foundation, taking into account the flexoelectricity effect. Timoshenko's first-order shear deformation theory is used to derive the formulations of the beam's forced vibration equation. The proposed theory and mechanical model are verified by comparing the numerical results of this work with those of the published data.

Dynamic vibration absorber (DVA) integrated with a piezoelectric stack energy harvesting subjected to base excitation is introduced in this paper. The system of dynamic vibration absorber and piezoelectric stack energy harvesting system (DVA-PSEH) has two functions, the first is to reduce vibrations for the primary system, and the second is to convert a part of the vibrational energy into electricity through the piezoelectric effect.

Shape and vibration controls of smart structures in structural applications have gained much attraction due to their ability of actuation and sensing. The response of structure to bending, vibration, and buckling can be controlled by the use of this ability of a piezoelectric material. In the present work, the static and dynamic control of smart piezolaminated beams is presented.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).

This article presents the forced vibration of composite beams reinforced by singlewalled carbon nanotubes (SWCNTs) and subjected to a moving mass. Considering the distribution of carbon nanotubes such as uniform (UD-CNT), functionally graded Λ (FGΛ-CNT) and X (FGX-CNT), three different beams are studied.

Vibration analysis of multi-span bidirectional functionally graded material (2D-FGM) beams subjected to a moving load is presented by using a high-order deformation theory. The material properties of the beam are assumed to vary continuously in the thickness and longitudinal directions by a power-law distribution. The dynamic response of the beam is computed with the aid of the Newmark method.

This paper further extends the CS-FEMDSG3 for static, free vibration, and dynamic response of the stiffened plate resting on viscoelastic foundation subjected to a moving vehicle. The viscoelastic foundation is modeled by discrete springs and dampers whereas the stiffened plate can be considered as the combination between the Mindlin plate and the Timoshenko beam elements.

In this present paper, the road profiles are generated according to the ISO 8606:2016 standard to compare the differential of the road profile when changing the conditions. The semi-active suspension techniques are the solution to this problem and capable of reducing road vibrations effectively. The vertical quarter car model is installed with semi-active suspension system using Electrorheological shock absorber (ER damper) also considered to study the response of the vehicle to the road profile.

The dynamic response to variable magnitude moving distributed masses of simply supported non-uniform Bernoulli–Euler beam resting on Pasternak elastic foundation is investigated in this paper. The problem is governed by fourth order partial differential equation with variable and singular coefficients. The main objective of this work is to obtain closed form solution to this class of dynamical problem.

This paper presented a method to reduce the torsional vibration of a shaft system with dynamic vibration absorber (DVA). A theoretical method was introduced to determine optimal parameters of the DVA, which included spring stiffness, viscous coefficient of damper, mass moment of inertia of the absorber, number, and radial position of springs and dampers. First, system equations of motion of the shaft and the DVA were elaborated using Finite Element method (FEM) and solved by Runge-Kutta algorithm to find the torsional vibration response.
