Dynamics of Water Absorbed in Polyamides

Macromolecules, 2012
We investigate the dynamics of water absorbed in amorphous and semicrystalline aromatic polyamide copolymers. The combination of dielectric spectroscopy and quasi-elastic neutron scattering experiments allows us to characterize the water dynamics over a wide range of temperatures (dielectric spectroscopy) and at microscopic length scales (neutron ...

Dynamic vibration absorber

The Journal of the Acoustical Society of America, 1988
A vibration damping arrangement for a structural member including leaf springs extending horizontally from a vibration absorber body adapted to be attached to the structural member. A set of horizontal-vibration-absorbing leaf springs extends in one horizontal plane while a set of vertical-vibration-absorbing leaf springs extends in another horizontal ...

Dynamics Analysis of Energy Absorbing Device Based on Damped Dynamics Vibration Absorber

Applied Mechanics and Materials, 2015
Nowadays, absorbing energy from vibration is one of the most promising technologies. In general, the vibrations may be very large, such as the vibrations of tall buildings, large flexible bridges, and ocean platform and so on in some environmental loading.

Tuned dynamic vibration absorber

The Journal of the Acoustical Society of America, 1997
A vibration absorber is provided for reducing noise and vibration emanating from an electric motor, or another vibrating object, and the surrounding structure to which it is mounted. The vibration absorber has a beam with a mass secured thereto. The vibration absorber is mounted externally to the motor, in a direction perpendicular to an axis of ...

The broadband dynamic vibration absorber

Journal of Sound and Vibration, 1982
The limited effectiveness of the linear passive dynamic vibration absorber is described. This is followed by an analysis producing the response of a primary system when a non-linear softening Belleville spring is used in the absorber. It is shown that the suppression bandwidth can be doubled by this means.

Optimal Cantilever Dynamic Vibration Absorbers

Journal of Engineering for Industry, 1977
This work considers the use of a double-ended cantilever beam as a distributed parameter dynamic vibration absorber applied to a single-degree-of-freedom system in the presence of sinusoidal forces. The problem is analyzed exactly and by an energy approach using a single mode approximation for the cantilever beam.

Dynamic Absorbers for Modern Powertrains

SAE Technical Paper Series, 2011
<div class="section abstract"><div class="htmlview paragraph">This paper describes the use of dynamic vibration absorbers in torque converters to reduce the torsional vibration levels of the vehicle drivetrain. The use of both tuned mass absorbers and centrifugal pendulum absorbers (CPA) are discussed. In the case of the tuned mass absorber,

Platelike Dynamic Vibration Absorbers

Journal of Engineering for Industry, 1975
Platelike dynamic vibration absorbers of novel design are described, and optimum values of their tuning and damping parameters are specified in graphical form. The dynamic absorbers are assumed to comprise either a circular or an annular damped plate that is loaded at its outer perimeter by a rigid annular mass.

A Thermoviscoelastic Dynamic Vibration Absorber

Journal of Applied Mechanics, 1998
A dynamic vibration absorber with a viscoelastic element is studied. The viscoelastic element is modeled as a material with memory in which the internal dissipative force depends on current, as well as previous deformations. The viscoelastic behavior is governed by two parameters: the relaxation modulus Go, and the relaxation time γ.
