Design and Analysis of Piezoaeroelastic Energy Harvester for Mid-Range Wind Velocity Applications Subjected to Random Excitations
摘要
Aeroelastic vibration is a viable source of energy using a piezoelectric transducer. When aeroelastic structures are subjected to wind induced vibrations, these vibrations are harnessed by the piezoelectric transducer to generate electrical output. Typically, these transducers operate effectively under constant wind speeds. However, natural wind conditions are often variable, changing in direction, magnitude, or both, which can significantly impact the power output of the transducer. This study focuses on harvesting energy from ambient vibrations, which are inherently random, using a galloping-basedPiezoaeroelastic energy harvester piezoaeroelastic energy harvesterEnergy harvester under mid-range wind speeds. A mathematical model of the aeroelastic structure underStochastic stochastic vibration is developed, and the effects of various parameters on energy generation are investigated.
