A Coupled Analysis of Nonlinear Vibration Energy Harvester Based on Predictor-Corrector Approach

Year: 2025

Type: article

Abstract: This paper presents a coupled analysis method for vibration energy harvesters based on predictor-corrector approach. To consider the coupling of vibration and electromagnetic systems, time-evolutions of system states are predicted, and coupling factors are evaluated from the predicted states. Then, the next system states are evaluated by solving the system's governing equations. The coupling factors are corrected using the predicted and computed states. It is shown that the proposed method can evaluate the performance of a vibration energy harvester with little computational burden, while the analysis results almost equal those of the conventional quasi-strong coupled analysis method. Moreover, the measurement results show that the proposed method can qualitatively simulate the behaviors of nonlinear vibration energy harvesters.
