Abstract: Vibration energy harvesting systems are using real ambient sources of vibration excitation. In our paper, we study the dynamical voltage response of the piezoelectric vibrational energy harvesting system (PVEHs) with a mechanical resonator possessing an amplitude limiter. The PVEHs consist of the cantilever beam with a piezoelectric patch. The proposed system was subjected to…
Abstract: This paper presents a hybrid piezoelectric wind energy scavenger with different cross-sectioned bluff bodies, to enhance the energy scavenging performance by coupling both the vortex-induced vibrations (VIV) and galloping phenomena. Theoretical, experimental and computational fluid dynamics (CFD) studies are conducted to investigate the energy scavenger performance with three combinations of the circular and square…
Abstract: This study performs a comprehensive parametric study and optimization of a piezoelectric wind energy harvester subjected to the conjunction of vortex-induced vibration (VIV) and galloping. The mathematical model of the harvester undergoing both the VIV and galloping is formulated, which is experimentally validated through the wind tunnel tests. The experimental results uncover that different…

Abstract: This paper examines the oscillations of a spherical pendulum with horizontal Lissajous excitation. The pendulum has two degrees of freedom: a rotational angle defined in the horizontal plane and an inclination angle defined by the pendulum with respect to the vertical z axis. The results of numerical simulations are illustrated with the mathematical model…
