Response analysis of undamped primary system subjected to base excitation with a dynamic vibration absorber integrated with a piezoelectric stack energy harvester

Dynamic vibration absorber (DVA) integrated with a piezoelectric stack energy harvesting subjected to base excitation is introduced in this paper. The system of dynamic and (DVA-PSEH) has two functions, the first reduce vibrations for primary system, second convert part vibrational into electricity through effect. mechanical electrical responses electromechanical are determined by complex amplitude method, then numerical simulations carried out investigate characteristics DVA-PSEH.
