Outline of Final Research Achievements

MR(Magneto-rheological) fluids are the suspensions with micron-sized ferromagnetic particles dispersed into carrier oil, and also are one of smart fluids which can be changed their rheological properties in reversible manner by applying magnetic field. Since the carrier medium is a liquid, the limits of the viscosity reduction and the operating temperature raising exist. In this study, to overcome the above limits and restrictions for the conventional MR fluids, novel "dry MR fluids without liquid medium" ; MR fluidic powder, mainly consisting of micron-sized carbonyl iron particles coated with nano-sized silica particles have been fabricated, featuring extremely low zero-field viscosity and higher operating temperature. The optimized dry MR fluid has been applied to the MR fluid brake of multi-disks type for a super-compact EV, and it has been realized that the developed dry MR fluid brakes have performed enough braking torque, high speed response and high controllability.

Academic Significance and Societal Importance of the Research Achievements

磁場に反応して粘性の変化するMR流体は、その特筆すべき機能性から種々の工学的応用が試され、また実用化もなされてきている。本研究では、その分散媒として油を用いることによる特性上の種々の限界や使用上の制約を克服するために、分散媒として液体を用いないで気体を用い流動性を向上した磁性微粒子の粉体からなるドライMR流体を新規に創製しており、機能性新素材の研究開発という面において学術的意義がある。また、創製したドライMR流体を小型EV用の四輪ブレーキに適用して優位性と有用性を実証しており、既存の技術を凌駕するかなり高度な革新的な制動技術の実現やEVの全電動化等に貢献することに繋がり、社会的意義も大きい。
