Vibration and wear particles analysis in a test stand
(2007-08-17)
Purpose - This paper aims to provide information on wear debris on oil and vibration analysis as predictive maintenance techniques. Design/methodology/ approach - The estate of a reducer is verified by analyzing the vibration ...
On synchrophasing control of vibration for a floating raft vibration isolation system
(2014-01-01)
A large-scale floating raft vibration isolation system installed on a flexible hull-like structure is described in this paper. Four vibration exciters, in which two counter rotating shafts with the same balanced masses are ...
On the spectrum of rail vibration generated by a passing train
(2017-01-01)
Recent work in rail vibration has investigated methods for estimating track support stiffness from trackside vibration. This vibration, induced by the passage of a train, is mainly due to the load applied by the wheels, ...
Recent Advances in Shock Vibration Isolation: An Overview and Future Possibilities
(2019-01-01)
Mechanical shock is a common problem that is present in many situations, such as ground motion, blast, explosions, crash, and impact. The development of passive, active, or adaptive control and isolation strategies for ...
Freezing of gait in Parkinson's disease: Evidence of sensory rather than attentional mechanisms through muscle vibration
(2016-08-01)
Introduction The role of proprioceptive integration impairments as the potential mechanism underlying Freezing of gait (FOG) in Parkinson's disease (PD) is still an open debate. The effects of muscle vibration (a well-known ...
On the control of vibrations using synchrophasing
(2013-09-30)
This paper describes the application of a technique, known as synchrophasing, to the control of machinery vibration. It is applicable to machinery installations, in which several synchronous machines, such as those driven ...
Harvesting Energy from Time-Limited Harmonic Vibrations: Mechanical Considerations
(2017-10-01)
Single-degree-of-freedom (SDOF) mechanical oscillators have been the most common type of generators used to harvest energy from mechanical vibrations. When the excitation is harmonic, optimal performance is achieved when ...
The correlation of vibration signal features in grinding of advanced ceramics
(2016-09-01)
Monitoring the grinding of ceramics using the vibration signal has been presented as an alternative for the diagnosis of the workpiece surface. This paper has the objective of studying the vibration signal through spectral ...
ON ACTIVE SYNCHROPHASING CONTROL OF VIBRATION FOR A FLOATING RAFT VIBRATION ISOLATION SYSTEM
(Int Inst Acoustics & Vibration, 2015-01-01)
A floating raft vibration isolation system installed on a flexible hull-like structure is described in this paper. Four vibration exciters, in which two counter rotating shafts with the same balanced masses are driven by ...
On the target frequency for harvesting energy from track vibrations due to passing trains
(2019-01-01)
There is an increasing desire to monitor the structural integrity of railway tracks and the supporting ballast and subgrade. Track vibration has been proposed as a potential energy source to power wireless sensors for this ...
