N2 - A centralized parameter model is established for the piezoelectric-magnetoelectric composite vibration energy convertor in the present work. The feasibility of the established model is comparatively studied with the theoretical calculation, the simulation results, as well as the experimental results. To achieve the optimal performance evaluated by the overall output power, the coupling strengths in three physical mechanisms of the piezoelectric, the magnetoelectric and the piezoelectric-magnetoelectric composite ones, are analyzed with considering and neglecting the structural differences respectively. And the coupling strengths are classified into three cases, such as the weak, the medium and the strong ones, determined by the ratio of the electromechanical coupling coefficient to the damping of the system. This work is believed to be greatly significant to the design of the PE-ME composite vibration energy convertor and self-powered devices.
