This article presents an optimal design of an exterior permanent magnet (PM) tubular machine for energy harvesting from vehicles suspension systems. By using a hybrid structure, in which, the mechanical damper remains and electrical components are attached to the damper's frame, the damping force and damping coefficient are still ensured while wasted kinetic energy is recovered. To maintain driving comfort and safety, the detent force and electromagnetic force must be minimized. The constraints for dimensions of the exterior PM tubular machine were obtained from an actual shock absorber from a school bus, a large-size vehicle. Different topologies were investigated to maximize the output power and power density, while the electromagnetic force was minimized and negative effects of the initial positions to the machine's performance were mitigated. Finite element analysis showed that maximum and average power from an optimal design were about 210.2 and 103.7 W, respectively. To verify the validity of the design, a prototype was fabricated and tested.

汽车悬挂系统能量收集新型外置永磁管式电机的优化设计

本文介绍了一种用于从车辆悬架系统中收集能量的外部永磁 (PM) 管状电机的优化设计。通过采用混合结构,其中机械阻尼器保留,电气元件附在阻尼器框架上,在回收浪费的动能的同时仍然保证阻尼力和阻尼系数。为了保持驾驶舒适性和安全性,制动力和电磁力必须最小化。外部 PM 管状机的尺寸约束是从一辆校车(一种大型车辆)的实际减震器中获得的。研究了不同的拓扑结构以最大化输出功率和功率密度,同时最小化电磁力和初始位置对机器的负面影响 s 性能得到缓解。有限元分析表明,优化设计的最大和平均功率分别约为 210.2 和 103.7 W。为了验证设计的有效性,制造并测试了原型。
