Abstract

This paper introduces a nonlinear model to analyze the free vibration and primary resonance of bimorph cantilever-based functionally graded magneto-electro-elastic material (FGMEEM) energy harvesters. Accounting for the effects of curvature and inertia nonlinearities, the coupled reduced equations of motion are obtained by employing the Ritz method. The obtained sets of initial value problems are then analytically solved using the method of multiple time scales for both the free vibrations and primary resonance cases. The analytical time histories of the system are compared by those determined numerically and excellent agreements between them are observed. Afterward, comparing the maximum output power that can be scavenged by traditional functionally graded piezoelectric harvesters to that of the present system, it is observed that the present system enjoys more efficiency higher than 70%.
