Recently, nonlinear tuned vibration absorber (NTVA) has been proposed as an extension of the conventional linear tuned vibration absorber for vibration mitigation in mechanical systems. It effectively suppresses vibration in wide ranges of excitation amplitudes. The present project implies studying the possibility to implement such an absorber by utilizing granular materials, e.g. in the form of a volume filled with sand. It is intended to conduct an experimental testing of such an absorber and identify its dynamic properties. The performance of the absorber for vibration suppression for a model continuous structure, e.g. a beam, will then be studied experimentally and theoretically.
Experimental testing will be done using conventional vibration measurement techniques, e.g. by getting frequency response functions, etc. Theoretical work implies using dynamics and vibrations theory for simple model structures, e.g. beams and rods.
