Design and Analysis of Electromagnetic Linear Actuation-Energy-Reclaiming Device Applied to a New-Type Energy-Reclaiming Suspension

In order to meet the increasing demand for high-performance and high-efficiency vehicles, this paper proposes a novel electromagnetic linear energy-reclaiming suspension technology based on McPherson independent suspension, analyzes its core component—ELA-ERD (Electromagnetic Linear Actuation Energy-Reclaiming Device). ELA-ERD, taking shock absorber piston rod as inner yoke, has compact structure reasonable layout by integrating structural features of suspension. paper, design process ELA-ERD is elaborated in detail. Aiming at problem over-saturation yoke magnetic density, method optimize circuit size within effective working area moving coil, thus effectively improving characteristics ELA-ERD. Moreover, effect potential energy reclaiming were studied using finite element software. The study law was carried out from perspective changes vibration frequency amplitude. addition, internal relationship between voltage velocity revealed work, coefficient Ke defined. Through calculation large amount model data, value applicable designed approximately set 4.5. This lays an important theoretical foundation follow-up studies.
