Test device for parametric pendulums with a view on wave energy harvesting

Abstract

The design of a test device for the study of the dynamics of pendulum systems is presented. Based on the external forcing amplitude and frequency parameter space diagram from a multi-mass pendulum system, the regions of interest for the study of rotations are determined. The forcing characteristics for a simple parametric pendulum are obtained and then adapted according to the available manufacturing possibilities. A forcing generation mechanism is proposed, and the resulting physical model is shown. It is concluded that the designed device is suitable for a wide variety of tests and that the design requirements are met.
