Endurance of Damping Properties of Foam-Filled Tubes [PDF]

Materials, 2015
The favorable energy-absorption properties of metal foams have been frequently proposed for damping or anti-crash applications. The aim of this paper is to investigate the endurance of these properties for composite structures, made by a metal or a hybrid metal-polymeric foam used as the core filling of a tubular metal case.

EFFECT OF PARTICLE SIZE AND PACKING RATIO OF PID ON VIBRATION AMPLITUDE OF BEAM [PDF]

Journal of Mechanical Engineering and Sciences, 2013
Everything in the universe that has mass possesses stiffness and intrinsic damping. Owing to the stiffness property, mass will vibrate when excited and its intrinsic damping property will act to stop the vibration.

Isolation and damping properties of magnetorheologic elastomers

Journal of Physics: Conference Series, 2009
This paper considers two systems based on a magnetorheological elastomer (MRE): a MRE isolator under a frequency varying harmonic excitation and a MRE Dynamic Vibration Absorber (DVA) mounted on a frequency-varying structure under a random excitation. It is shown that the commandability of the elastomer improves the isolation performances in the first ...

Damping Properties of the Hair Bundle [PDF]

AIP Conference Proceedings, 2011
The viscous liquid surrounding a hair bundle dissipates energy and dampens oscillations, which poses a fundamental physical challenge to the high sensitivity and sharp frequency selectivity of hearing. To identify the mechanical forces at play, we constructed a detailed finite-element model of the hair bundle.

Vibration analysis of elevator rope with vibration suppressors (Identification of flexural rigidity, viscous damping and structural damping)

Nihon Kikai Gakkai ronbunshu, 2021
When an elevator rope for a high-rise building is forcibly excited by the displacement of the building induced by wind force and/or by long-period ground motion, rope displacement becomes large even if the ground acceleration and the building ...

Damping properties of the breathing mode in 208Pb

Physics Letters B, 1992
Abstract We study the properties of the isoscalar monopole resonance in 208 Pb, within the framework of a self-consistent model employing a Skyrme force. Including the coupling of the resonance to a set of particle-hole-phonon configurations, we obtain both a good description of the strength function of the mode and a consistent accout of the ...

Enhancing damping properties of Mg–Sn–Y alloys: The role of metastable clustering

Journal of Materials Research and Technology
The damping properties of Mg–Sn–Y alloys with varied Sn/Y atomic ratios and heat-treatment processes have been studied. In the as-cast state, the alloy with a Sn/Y ratio of 3:1 exhibits the highest damping property in the low strain region due to the low

Analytical modeling and numerical analysis of thermoelastic damping in ultrathin elastic films due to surface effects

Scientific Reports, 2023
Analytical techniques used for estimating thermoelastic damping by incorporating both mechanical and thermal interactions between surfaces and the rest of the bulk are intricate and challenging due to the limited understanding of the damping mechanisms ...
