An Analysis of the Gimballed Horizontal Pendulum System for Use as a Rotary Vibrational Energy Harvester


Conference Paper

© 2020, Society for Experimental Mechanics, Inc. This paper examines a gimballed horizontal pendulum for use as an energy harvester. It can be designed for threshold escape behavior rather than the conventional method of matching frequencies. A nonlinear electromechanical model is developed to study the system’s equilibrium states as a function of tilt angle. Bifurcation diagrams are generated to illustrate these equilibria and their associated stability. A bifurcation point is solved for analytically and the implications for an energy harvester, one that can be designed to jump across stable attractors based on forcing amplitudes, are discussed.
