Influences of system parameters on energy harvesting from autoparametric absorber. Numerical research

Mitura A., Kecik K.

Vibrations in Physical Systems

2016

Vol. 27

281--286

In the paper a numerical analysis of an autoparametric system is presented. The two main elements of a tested system are the pendulum (tuned mass absorber) and an energy harvester. The electromechanical model takes into account these both effects. Numerical simulations are made in a MATLAB software environment. The obtained results allowed estimation of influence of the system parameters on efficiency of energy harvesting.

Influences of system parameters on energy harvesting from autoparametric absorber. Experimental research

In the paper an experimental analysis of an autoparametric system dedicated to vibration suppression and energy recovery is presented. The main part is an electromagnetic energy harvester. Its properties were defined by quasi static and dynamic tests. The obtained results show influence of selected parameters on energy recovery level. The experimentally identification of electromechanical coupling coefficient which couples mechanical and electrical systems is done.
