Simultaneous vibration suppression and energy harvesting of vehicle suspension systems: status and prospects

Abstract

Suspension is one of key components in vehicles, which has the dual functions of load bearing and vibration suppression. As for traditional suspension systems, viscous liquid or dry friction damper is always used to convert vibration energy into heat which is dissipated to achieve vibration reduction. In this case, electric energy is wasted, which is especially unfavorable for new
energy vehicles. In the past decade, novel suspension systems that can both suppress vibration and harvest electrical energy have received high attention and extensive research. In order to comprehensively know the latest progress in synchronous vibration suppression and energy harvesting (SVSEH) of vehicle suspensions, this paper reviews the development history of vehicle
suspensions and summarizes the potential energy that can be collected from road excitations by vehicle suspensions. Then the research status on energy-regenerative suspensions is focused on. In the end, current technical challenges of SVSEH of vehicle suspensions are presented and future directions are discussed. The contribution of this paper is to help domestic researchers to
quickly and accurately grasp current status of this field and provide important ideas for the development of new vehicle suspensions.
