Abstract

In this research, a Energy Harvesting system was introduced in which two console beams coupled with Piezoelectric layers are connected to a rotating rigid disk. First, the system equations were written using the electromechanical Lagrange equations and then solved by exact solution and resonance approximation of the exact solution methods. The Energy Harvesting system was also simulated in software. The effect of angular velocity on resistance, voltage and optimal power was investigated and observed that increasing angular velocity, the optimal resistance and voltage first decrease and then increase, but the optimal power first increases and then decreases. Optimal minimum resistance and voltage and maximum optimal power are obtained at 44 rad/s. The results showed that in this system in order to produce absolute maximum power of 0. 094 W, electrical resistance of 1115 Ω is required. Power were also evaluated versus electrical voltage and resistance. Moreover, comparison of the results of the three methods showed very good agreement between the results of solving equations and simulation and resonance approximation solution responses are simpler than exact solution ones and have negligible error.
