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, ...
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 ...
Development of an instrumentation system embedded on FPGA for real time measurement of mechanical vibrations in rotating machinery
(2012-11-23)
The real-time monitoring of events in an industrial plant is vital, to monitor the actual conditions of operation of the machinery responsible for the manufacturing process. A predictive maintenance program includes condition ...

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 ...
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 ...

Damage assessment in a sandwich panel based on full-field vibration measurements
(Academic Press, 2018)
Different studies have demonstrated that vibration characteristics are sensitive to
debonding in composite structures. Nevertheless, one of the main restrictions of vibration
measurements is the number of degrees of ...
