Energy harvesting will become more and more essential mechanical vibration applications
of many devices. The vibrations can be converted by appropriate devices into electrical
energy, which can be used as a power supply instead of ordinary ones. This paper investigates
a dynamical system associated with two devices: a piezoelectric device and an electromagnetic
one. These devices are connected with a nonlinear damping spring pendulum
with 2DOF, in which its supported point moves in a circular path. The equations of motion
are obtained using Lagrange’s equations of the second kind. The asymptotic solutions of these
equations are obtained up to the third approximation utilizing the perturbation approach of
multiple scales. The comparison between these solutions and the numerical ones reveals high
consistency between them. The steady-state solutions are obtained, and their stabilities are
tested. The influences of the excitation amplitudes, the damping coefficients, and the different
frequencies on energy harvesting devices outputs are examined and discussed. The work is
essential due to its significance in real-life applications. The developed methodology and obtained
results can be useful in various applications like power supply of sensors and charging
electronic devices.
