Dynamical behavior and optimization of a nonlinear vibration absorber
(2016-10-01)
The paper concerns the introduction of cubic nonlinearity into a vibration absorber to improve its effectiveness. The nonlinear stiffness is offered by a thin clamped circular plate which undergoes large flexural deflection. ...
Combining active control and synchrophasing for vibration isolation of a floating raft system: An experimental demonstration
(2020-01-01)
Vibration isolation of a floating raft system typically found in a marine application is of concern in this paper. Housed on the raft are electrical motors each driving two counter rotating shafts with eccentric masses ...
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 ...
Polyphenoloxidase activity in peaches after vibration
(2013-09-19)
The vibration during transportation is one of the main causes of fruit damage. The actual methodologies used for damage evaluation in fruits seem to be subjective, since most of them are based on visual evaluation. In this ...
Evaluation of cracks caused by mechanical vibrations in buildings
(Springer, 2014-03-01)
The problem of cracks in building plays a very important rule in civil engineering and architecture areas. Mechanical vibrations and its effects should be monitored to prevent major damages. This kind of problem affects ...
Narrowband feedback for narrowband control of resonant and non-resonant vibration
(2016-08-01)
This paper presents a simple feedback methodology that uses second order filters to control narrowband resonant and non-resonant vibration of a structural system. In particular, a single degree-of-freedom system is studied ...
Acute effect of Whole-body vibration in a female dog with metritis
(Univ Fed Rio Grande Do Sul, 2017-01-01)
Background: Whole-body vibration is a modality of exercise used in humans for therapeutic purposes or to increase physical performance. In veterinary medicine there are only a few reports on the use of this technology. The ...
On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...
Vibration Control of a Floating Raft System by Synchrophasing of Electrical Machines: An Experimental Study
(2018-08-01)
This paper describes an experimental investigation into the vibration control of multiple electrical machines installed on a large-scale floating raft system. Vibration transmission to a flexible hull-like structure that ...
An investigation into the simultaneous use of a resonator as an energy harvester and a vibration absorber
(Elsevier B.V., 2014-02-28)
A mass-spring-damper system is at the core of both a vibration absorber and a harvester of energy from ambient vibrations. If such a device is attached to a structure that has a high impedance, then it will have very little ...
