Abstract

Harvesting energy by PIEZOELECTRIC materials is nowadays an efficient way for powering low-power electronic devices. Required energy for sensors, used in condition and health monitoring of bridges and other civil infrastructures, can be examples of the energy harvesters. This study aimed to improve the PIEZOELECTRIC-based ENERGY HARVESTING on civil infrastructures, especially on bridge structures. In this investigation, harvesting energy from the vibrations of a bridge under MOVING CONSECUTIVE MASSES is studied. Harvesting energy is carried out through a cantilever beam with PIEZOELECTRIC patch which is installed at the middle of a simply supported bridge. Governing equations for vibration of an Euler-Bernoulli beam under MOVING CONSECUTIVE MASSES are derived. The inertial effects, including centrifugal and coriolis forces are considered. For verification, the results of the numerical solution of the moving mass problem are compared to the experimental tests data of the literature. The harvester is modelled by a cantilever beam with PIEZOELECTRIC patch under base excitations which are calculated from vibrations of the bridge mid-point. The obtained equations are then solved in MATLAB environment by using the fourth order Runge-Kutta method. The calculated induced voltages are compared with those obtained from experiment. A good degree of accuracy is observed.
