Vortex-induced vibration (VIV) is used by piezoelectric energy harvesters to generate electricity from wind and water flow. In this study, we introduce the nonlinear magnetic force into develop a monostable VIV transducer. We build distributed-parameter model based on Euler-Bernoulli beam theory Kirchhof's law analyze dynamic responses of magnetic-coupling harvester (MCPEH). Model results show that performance MCPEH varies greatly with increase load resistance length PZT. There are two...
This paper studies a novel enhanced energy-harvesting method to harvest water flow-induced vibration with tandem arrangement of two piezoelectric energy harvesters (PEHs) in the direction flowing water, through simulation modeling and experimental validation. A mathematical model is established by individual-equivalent single-degree-of-freedom models, coupled hydrodynamic force obtained computational fluid dynamics. Through analysis, variation rules frequency, amplitude, power generation...
