Thoracic vibrations in stingless bees (Melipona seminigra): resonances of the thorax influence vibrations associated with flight but not those associated with sound production
(COMPANY OF BIOLOGISTS LTD, 2008)
Bees generate thoracic vibrations with their indirect flight muscles in various behavioural contexts. The main frequency component of non-flight vibrations, during which the wings are usually folded over the abdomen, is ...
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 ...
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 ...
Control of relative vibration between flexible appendages using passive and semi-active isolation
(Elsevier, 2017-12)
Relative vibration between two flexible subsystems can be detrimental to the performance of many engineering applications, such as optics-based instruments, machine tools, or adjacent industrial structures sharing piping. ...
On the detailed design of a quasi-zero stiffness device to assist in the realisation of a translational Lanchester damper
(2022-02-01)
A translational Lanchester damper is a device that adds damping to a structure at a point using a series combination of a viscous damper and a mass. The problem in the practical realisation of such a device is that a ...
A straightforward method for tuning of Lyapunov-based controllers in semi-active vibration control applications
(Elsevier, 2013-11-15)
Lyapunov-based control is an attractive strategy for semi-active vibration control as it has a mathematical basis ensuring stability in the sense of Lyapunov and great flexibility in the design. Unfortunately, that flexibility ...
Impedance-based damage detection under noise and vibration effects
(2018-05-01)
The electro-mechanical impedance technique has been extensively studied in recent decades as a non-destructive method for detecting structural damage in structural health monitoring applications using low-cost piezoelectric ...
An efficient modal control strategy for the active vibration control of a truss structure
(2007-11-16)
In this paper an efficient modal control strategy is described for the active vibration control of a truss structure. In this approach, a feedback force is applied to each mode to be controlled according to a weighting ...
Chaos control via state-dependent riccati equation method applied a non-ideal vibration absorber coupled to a nonlinear oscillator
(2015-01-01)
The non-ideal vibration absorber system coupled to a nonlinear oscillator is proposed in the paper. This system is demonstrated with a chaotic behavior and we present the control technical for the chaos stabilization. The ...
Design of a control system using linear matrix inequalities for the active vibration control of a plate
(Sage Publications Ltd, 2006-01-01)
The study of algorithms for active vibration control in smart structures is an area of interest, mainly due to the demand for better performance of mechanical systems, such as aircraft and aerospace structures. Smart ...
