Abstract
We present an experimental setup along with a simulation environment for piezoelectric cantilevered Energy Harvesting structures under the influence of a stationary rotation.We explain the physical effects that lead to changes in the natural frequencies of the harvester. Consideration of the effects by the Finite Element Method is outlined. For the computation of damped eigenfrequencies, we exploit a model order reduction scheme based on a modal truncation technique, extended to piezoelectric structures. Parameters that influence the tuning behavior are identified and simulation based parameter studies are presented.
