The aim of this paper is to present a
methodology for implementing the high-energy orbits
which is still an open problem for nonlinear energy
harvesters. To achieve it, this paper presents a new
design of system with a flag configuration which
potential function is shaped with the use of elastic
elements. We have identified the lift force in FEM for
wide spectrum of air velocities and used it as excitation
in dimensionless mathematical model. On this basis we
have conducted simulations of energy harvesting
effectiveness. In the second part of the work, we
focused on identifying the coexisting solutions. Due to
the existence of high-energy orbits and low-energy
orbits, we conducted simulations to investigate the
possibility of changing the orbit. We used the Impulse
Excitation Diagram here, but supplemented it with
multi-colored probability distribution maps illustrating
the possibility of achieving a stable orbit at given
numerical values of the impulse amplitude and
duration for various values of air flow velocity. The
use of probability distribution maps allow to select the
optimal impulse characteristics from the point of view
of the energy necessary for its initiation.
