A comparison of two nonlinear damping mechanisms in a vibration isolator
(2013-02-04)
The vibration transmissibility characteristics of a single-degree-of- freedom (SDOF) passive vibration isolation system with different nonlinear dampers are investigated in this paper. In one configuration, the damper is ...
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 ...
Maintenance of a reducer by vibration and wear particles analysis
(2006-06-20)
Purpose - The purpose of the paper is to provide information on wear debris on oil and vibration analysis as predictive maintenance techniques in reducer. Design/methodology/approach - The estate of a reducer is verified ...
Active vibration control using delayed resonant feedback
(2013-09-01)
Delayed feedback (DF) control is a well-established technique to suppress single frequency vibration of a non-minimum phase system. Modal control is also a well-established technique to control multiple vibration modes 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 ...
Stochastic field processes in the mathematical modelling of damped transmission line vibrations
(1987-12-01)
Wind-excited vibrations in the frequency range of 10 to 50 Hz due to vortex shedding often cause fatigue failures in the cables of overhead transmission lines. Damping devices, such as the Stockbridge dampers, have been ...
On the influence of the mode-shapes of a marine propulsion shafting system on the prediction of torsional stresses
(2013-05-13)
Torsional vibration predictions and measurements of a marine propulsion system, which has both damping and a highly flexible coupling, are presented in this paper. Using the conventional approach to stress prediction in ...
A Short Note on Transverse Vibrations of a Shaft Carrying Two (or One) Disk Excited by a Nonideal Motor
(Asme-amer Soc Mechanical Eng, 2009-01-01)
The paper presents a number of numerical simulations of the transverse vibrations of two (or one) imbalanced rotors forced by an electric motor with limited power supply, during the passage through of the two resonance ...
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 ...
TMJ Vibrations in Asymptomatic Patients Using Old and New Complete Dentures
(Wiley-Blackwell, 2010-08-01)
Purpose: The aim of this study was to assess the presence of temporomandibular joint (TMJ) noises in subjects with severe bone resorption, who have worn the same complete dentures for over 10 years, and 5 months after ...
