摘要：

Vibration energy is scavenged by a beam system based on magnetostrictive material (MsM). The system consists of interconnected substructural beams (aluminum and magnetostrictive layers) with a neutral stress axis shifted away from the axis of symmetry of the magnetostrictive beam. The coil that generates the electromotive force is wound on the composite beam. The study investigates the effects of a tip mass placed at the end of the beam and the beam thickness influence. Multiple solutions are found for high amplitudes, and the optimal configuration of the operating conditions is proposed. In addition, the sensitivity of the system to the initial conditions is compared for the first three resonance areas, leading to determination of two types of solutions with different levels of power output.
