Abstract
In this article we explore the nonlinear dynamics of a parametric pendulum considering a reciprocating external excitation. Reciprocating motion can be found in a wide range of industrial machines, including engines and pumps, where a crank-rod system is used to convert circular motion into linear motion or vice versa. We focus our study in energy harvesting by means of pendular devices, thus we concentrate in steady state rotations of the pendulum, which are highly energetic. Although reciprocating excitation is similar to the simple sinusoidal, a different and more complex rotational behavior is observed for certain combinations of forcing and damping parameters. It is shown that a new rotation zone is present in the control space of parameters, which increases the possibilities of energy extraction.
