EXPERIMENTAL OBSERVATION OF NONLINEAR VIBRATIONS USING A CLOSED-LOOP VIBRATION SYSTEM
(Polish Acad Sciences, 2015-12-01)
This paper presents experimental observation of nonlinear vibrations in the response of a flexible cantilever beam to transverse harmonic base excitations around its flexural mode frequencies. In the experimental setup, ...
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 ...
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 ...
Experimental characterization of a nonlinear vibration absorber using free vibration
(2016-04-14)
Knowledge of the nonlinear characteristics of a vibration absorber is important if its performance is to be predicted accurately when connected to a host structure. This can be achieved theoretically, but experimental ...
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 ...
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 ...
SDRE applied to position and vibration control of a robot manipulator with a flexible link
(2016-01-01)
This paper presents position and vibration control of a flexible robot composed of two rigid and one flexible links. Position is controlled by the current applied to the DC motor armature. To control vibrations of the ...

(Polish Soc Theoretical & Applied Mechanics, 2016-01-01)
This paper presents position and vibration control of a flexible robot composed of two rigid and one flexible links. Position is controlled by the current applied to the DC motor armature. To control vibrations of the ...
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 ...
On synchrophasing control of vibration and sound radiation for a floating raft vibration isolation system
(2014-01-01)
For the purpose of solving the problems of vibration transmission and sound radiations in ships, synchrophasing control technology was presented. The phases of multiple rotating or reciprocating machines installed on a ...
