Nonlinear dynamics of piezoelectric based energy harvester under parametric and galloping instabilities

Abstract

The present study is attempted to utilize the geometric and inertial nonlinearities along with modal interactions for piezoelectric based energy harvesting by extracting energy from parametric and galloping instabilities In this research work four nonlinear problems related to piezoelectric energy harvester systems have been investigated In all the cases the harvester system consists of a vertical cantilever beam with piezoelectric patches and attached mass at an arbitrary position In the...
