With the development of electric vehicles, the energy harvesters of vehicle’s suspensions have been widely investigated. However, most of the existing energy harvesters have replaced the original damper of the suspensions, which reduces vehicle safety. This paper proposes a magnetic energy-harvesting suspension (MEHS) for vehicles, with the advantages of high vehicle safety and a compact structure, which consists of a passive suspension and a harvester. In this paper, the working principle and the structure of the MEHS are introduced. To better analyze the magnetic field, the magnetic flux circuit model is established by combining the magnetic field division method with the magnetic equivalent circuit model. Furthermore, a dynamic model for a two-degree-of-freedom quarter-vehicle with the MEHS is built to analyze the energy-harvesting characteristics and the damping characteristics. A prototype of the quarter-vehicle that is considering the tire stiffness, is designed and manufa...

车辆磁能收集悬架的设计，分析和原型设计

随着电动汽车的发展，对车辆悬架的能量收集器进行了广泛的研究。但是，大多数现有的能量收集器已取代了悬架的原始减震器，这降低了车辆的安全性。本文提出了一种汽车磁能收集悬架（MEHS），它具有较高的车辆安全性和紧凑的结构，该结构由被动悬架和收割机组成。介绍了MEHS的工作原理和结构。为了更好地分析磁场，将磁场划分方法与等效磁路模型相结合，建立了磁通量电路模型。此外，建立了带有MEHS的两自由度四分之一车辆的动力学模型，以分析能量收集特性和阻尼特性。设计并制造了考虑轮胎刚度的四分之一车辆原型。
