摘要: Energy harvesting from broadband excitation, such as aircraft noise, and low frequency human motion, has gained significant interest recently. Vibro-impact is one of the methods used to improve capability harvester by high conversion. The present paper analyses effect vibro-impact within a coupled beam system. system base excited localised non-linearity induced at point impact. Modal reduction techniques are applied reduce computational time. localisation on performed varying parameters, for example amplitude clearance stiffness between beams.
