Abstract

A compact bistable galloping oscillator is proposed for enhanced power generation from concurrent wind and base vibration. The harvester consists of a D-shaped bluff body attached to a piezoelectric cantilever. Repulsive magnetic interaction is introduced between the bluff body and a fixed windward support to bring nonlinear bistability. An aeroelectro- mechanically coupled model is established and experimentally validated. Both experimental measurements and model predictions demonstrate that the synchronization bandwidth for efficient energy harvesting from concurrent wind and base vibration can be substantially extended.
