Abstract
To improve suspension performance and address the sedimentation issue of magnetorheological fluids, a Dual-Coil Built-in Valve Magnetorheological Damper with Anti-Settlement Characteristics (DC-BIV-MRD/AS) is proposed in the study. The anti-settling structure of the DC-BIV-MRD/AS was designed. The magnetic circuit model and the damping force model of the DC-BIV-MRD/AS were established. Finite element analyses was carried out. A prototype of DC-BIV-MRD/AS was manufactured. Experimental research on the anti-settling and damping characteristics of the DC-BIV-MRD/AS were carried out. The damping characteristics results show that the damping force of the DC-BIV-MRD/AS can reach 3350 N and the dynamic range is about 3.92, which meet the design requirements. The theoretical values of the DC-BIV-MRD/AS damping characteristics show good agreement with the experimental values under varying current. In the anti-settling characteristic experiment, the results of the HCMN-MRF application in the damper with the solenoid switched on for five days are higher than the results of the application with the solenoid switched off and left in the damper for five days. The solenoid device has an positive effect on improving the stability of the damper settlement.
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.
