悬架是汽车中的核心关键部件，具有承载和减振的双重功能。传统的悬架系统采用黏性液体或干摩擦阻尼器将振动能量转化为热量耗散出去实现减振，造成能量浪费，这尤其对新能源汽车不利。近十年来，既能抑制振动又能收集电能的新型悬架系统受到了高度关注和广泛研究。为了全面掌握汽车悬架同步振动抑制与能量收集技术领域的最新进展，回顾汽车悬架的发展历程，总结汽车悬架从路面激励中可收集的振动能量，重点梳理汽车能量回收悬架技术研究现状，探讨当前面临的技术挑战并对未来发展方向进行了展望。该研究有助于国内同行快速准确地掌握本领域的技术现状，有望为国内新型汽车悬架技术的发展提供重要参考。

Simultaneous Vibration Suppression and Energy Harvesting of Vehicle Suspension Systems: Status and Prospects

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 the work 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.
