“…A MATLAB/SIMULINK model, exploiting a blockoriented substructuring technique (Velardocchia et al, 2008), has been made to properly study the dynamic behavior of the device. The model takes into account the different phenomena involved in the energy harvester behavior like magnetic interactions between magnets and between magnets and coils, interactions with the electrical load, moving magnet dynamic, pneumatic forces, friction, etc.…”

This article presents a very compact electromechanical wideband energy harvester optimized for tire applications. The device exploits an asymmetric magnetic spring to be adaptive and effective at almost any vehicle speed. The device has been simulated through an experimentally validated SIMULINK block-oriented model. The simulation takes into account nonlinear dynamic and adaptive resonant behavior of the seismic mass, electromagnetic, and magnetostatic coupling between floating magnetic mass and coils, and the transfer of the generated power to an external load by means of a nonlinear circuit interface. A particular focus on the pneumatic effect on the floating magnet has been made. A convenient choice of clearance between moving and fixed parts can be used to create an effective air brake preventing or softening shocks with end stops and to modify system dynamic. A nonlinear equivalent spring dashpot model of the pneumatic effect and a method to estimate its parameters from geometry have been proposed. An analysis of different nonlinearities of the system at different vehicle speed and a study on the combined effect of softening and hardening behavior of the device have been performed and discussed.

“…The energy harvester simulator is built in Simulink using a block-oriented logic (Velardocchia et al, 2008): every system component interacts with the other ones by a mutual data exchange about actions and reactions between the same components. This kind of logic partitioning of the model emphasizes interactions between system components giving a quick and easy comprehension of cause-and-effect relationships.…”

A strong integration between different design tools is desirable to improve the work of engineers, reducing the number of errors and speeding up the design process. In this article, the authors present a strong integration between three-dimensional computer-aided design models and multidomain simulation applied to the design of a magnetomechanical energy harvester. A MATLAB framework controls a block-oriented Simulink model, drives the Finite Element Method Magnetic simulation and manages the updating of the SolidWorks computer-aided design models of the device. The parameters involved in the different simulations and in the computer-aided design models are stored in a unique data file. Moreover, constructive drawings are automatically updated and are immediately suitable for tolerance and design constraint checks and also for the effective prototyping of the device. Constructed prototypes are immediately suitable to validate the performance predicted by the model.
