Abstract

In the last two decades, legislation that regulates carbon dioxide emissions are getting more and more stringent. In order to meet these regulations, fuel efficiency must be increased. This can be possible using devices that recover otherwise wasted energy. In this study, an electromagnetic regenerative shock absorber is analyzed. The device is capable of converting the vibrational energy, usually wasted as heat in conventional dampers, into electrical energy. The objective of this work is to develop a Matlab® model of the system in order to evaluate the gain in terms of harvested energy. The dynamic performance of the selected regenerative shock absorber integrated in the suspension system is evaluated. This includes an investigation of the ride filtering capability of the apparatus in order to highlight the behaviour in terms of comfort and handling. The influence of road roughness and vehicle speed on the aforementioned outcomes are investigated.
