Simultaneous optimization of topology and supplemental damping distribution for buildings subjected to stochastic excitation
(2021)
Supplemental damping devices present an attractive means to improve the structural system. Typically, dampers are designed after the structural system is selected, and they are added to increase structural damping and ...
The effect of spectral shape on damping modification factors
(2020)
The main objective of this study is to investigate the effect of spectral shape on damping modification factors η used in equivalent static and response spectrum analyses of structures with damping ratios that are different ...
Aeroelastic behavior of a wing with a magnetorheological hysteretic model to the damping
(2011)
This paper shows the application of a hysteretic model for the Magnetorheological Damper (MRD) placed in the plunge degree-of-freedom of aeroelastic model of a wing. This hysteretic MRD model was developed by the researchers ...
Dynamic analysis for different finite element models of beams with viscoelastic damping layer
(2014-01-01)
Many new viscoelastic materials have been developed recently to help improve noise and vibration levels in mechanical structures for applications in automobile and aeronautical industry. The viscoelastic layer treatment ...

On the dynamic behaviour of the "click" mechanism in dipteran flight
(Academic Press Ltd Elsevier B.V. Ltd, 2011-11-21)
In this paper, the dynamic behaviour of the "click" mechanism is analysed. A more accurate model is used than in the past, in which the limits of movement due to the geometry of the flight mechanism are imposed. Moreover, ...

Existence, uniqueness and exponential decay of solutions to kirchhoff equation in ℝn
(2016-09-12)
We discuss the global well-posedness and uniform exponential stability for the Kirchhoff equation in ℝn (Formula presented) The global solvability is proved when the initial data are taken small enough and the exponential ...
Modeling inherent damping in nonlinear dynamic analysis
(2017)
Modeling of inherent damping in nonlinear dynamic analysis has generated significant interest over the past 35 years, and there is little agreement as to the approach that should be used. In most cases, it is assumed that ...
Design of PSS and TCSC Damping Controller Using Particle Swarm Optimization
(Springer, 2016-10-01)
In this paper, we propose a methodology to tune power system stabilizers and thyristor-controlled series capacitor damping controllers simultaneously. The particle swarm optimization algorithm is incorporated into a power ...
