Abstract

In order to enhance the braking torque of the magnetorheological brake, a composite disk-type magnetorheological brake with a secondary coil is proposed and designed. In order to analyze the actual braking torque of the main coil and secondary coils in various operating modes and the corresponding energy efficiency ratio, the magnetic circuit design and mathematical model are completed first, followed by computational electromagnetics simulation and experimental validation. The experimental results demonstrate that with the main coils connected in series and energized alongside the secondary coils, the optimized configuration achieves a 3.3% increase in braking torque, albeit with an 8.5% reduction in energy efficiency ratio. The braking torque increases by 3.2% when operating the main coil in parallel configuration while co-activating the secondary coil, although this setup induces a 3.3% drop in the overall energy efficiency ratio.

复合盘式磁流变制动器制动转矩及能效比试验研究

为了提高磁流变制动器的制动力矩，提出并设计了一种带二次线圈的复合盘式磁流变制动器。为了分析主线圈和副线圈在各种工作模式下的实际制动转矩及相应的能效比，首先完成磁路设计和数学模型，然后进行计算电磁学仿真和实验验证。实验结果表明，当主线圈串联并与副线圈一起通电时，优化后的配置使制动扭矩增加了3.3%，但能效比降低了8.5%。当主线圈并联运行时，副线圈协同激活，制动扭矩增加3.2%，尽管这种设置导致整体能量效率比下降3.3%。

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
