| description |
A computational approach for the evaluation of the electro-mechanical response of levitation based vibration energy harvesters is presented in this paper. The key aspects of the design of levitation based energy harvesters, such as the existence of the resonance phenomenon, the influence of damping in the system response, the magnetic force nonlinearity and the calculation of the magnetic flux derivative for multi-magnet configurations are addressed. The evolution in time of the electromechanical variables is investigated through a hybrid numericalanalytical approach. The evaluation of the levitational force and the magnetic flux derivative is done through a nonlinear model based on the finite element method. A performance assessment is done by comparing the results obtained with the present formulation against measurements; a physical prototype of a multi-pole-multi-coil harvester is built ad hoc. An excellent agreement between the mathematical model and the experiments was found. |
