On vibration mitigation and energy harvesting of a non-ideal system with autoparametric vibration absorber system
(2018-10-01)
This paper demonstrates that vibration mitigation and energy harvesting can be achieved simultaneously by using of an electricity-generating from autoparametric vibration absorber system (AVAS) and non-ideal system (NIS). ...
Using passive control by a pendulum in a portal frame platform with piezoelectric energy harvesting
(Sage Publications Ltd, 2018-08-01)
This work presents a passive control strategy using a pendulum on a simple portal frame structure, with two-to-one internal resonance, with a piezoelectric material coupling as a means of energy harvesting. In addition, ...
Nonlinear piezoelectric vibration energy harvesting from a portal frame with two-to-one internal resonance
(2017-09-01)
In the few decades, the study of electro-mechanical systems which are capable to extract energy from an operating system in the environment has been of most importance. In this work, we present the extraction of energy ...
Using saturation phenomenon to improve energy harvesting in a portal frame platform with passive control by a pendulum
(2016-01-01)
A new model of energy harvester based on a simple portal frame structure subjected to saturation phenomenon is presented. Energy is collected via a piezoelectric device whose nonlinearities are considered in the mathematical ...
