Research Abstract

Waveform to be scavenged was studied in the wave energy scavenging by parametric pendulum. We verified that the pendulum can rotate under a multifrequency excitation or an excitation based on the measured sea wave data. In addition, the dependence of rotation on the excitation was clarified numerically and experimentally.
