Abstract

To study the wear mechanism of the magnetorheological brake, a set of composite disc magnetorheological brake system is proposed for easy disassembly and a brake wear mechanism experimental setup is constructed to experimentally study the effects of the number of braking times, the material of the brake disc, and the size of the magnetorheological fluid working clearance on the wear of the brake disc. The experimental results show that: with the increase of the number of braking times, the surface roughness of the brake disc gradually becomes smaller, the wear on the surface of the brake disc will worsen, and the braking torque of the magnetorheological brake will become larger. With the increase of the hardness of the brake disc, the surface wear of the brake disc will reduce accordingly. With the reduction of the magnetorheological fluid working clearance, the surface wear of the brake disc will worsen accordingly. The results of this study are of great significance for the improvement of the service life of the magnetorheological brake.

复合盘式磁流变制动器磨损机理研究

为研究磁流变制动器的磨损机理，提出了一套便于拆卸的复合盘式磁流变制动系统，并建立了制动器磨损机理实验装置，实验研究了制动次数、制动盘材料、磁流变液工作间隙大小对制动盘磨损的影响。实验结果表明：随着制动次数的增加，制动盘表面粗糙度逐渐变小，制动盘表面磨损加剧，磁流变制动器的制动力矩变大。随着制动盘硬度的增加，制动盘的表面磨损也会相应减少。随着磁流变液工作间隙的减小，制动盘的表面磨损也会随之加重。研究结果对提高磁流变制动器的使用寿命具有重要意义。

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.
