本研究では，外部磁場に応答して粘性変化が期待される新しい材料として磁気粘性コンパウンドを開発し，その基礎物性を評価した．また，提案材料を流体ブレーキに応用し，磁場に応じたブレーキトルク特性や応答性等の評価を行った．さらに，提案材料を用いた可変減衰防振マウントの作製及び防振性能評価を行った．磁気粘性コンパウンドの生成については，磁性粒子の沈殿回避のための材料組成を見出すことができた．流体ブレーキの応用については，従来と同程度もしくはそれ以上のトルクを伝達可能な装置を構成できる可能性が示された．防振マウントについては，既存材料と同等の減衰力可変性に加え，支持剛性の可変性を新たに見出すことができた．
In the present study, magnetorheological compounds (MRCs) were developed and their typical properties were investigated experimentally by using a rotational viscometer specially designed for high-viscous materials. While keeping similar viscosity change property as the magnetorheological fluid due to the externally applied magnetic field, sedimentation problem of the dispersed magnetic particles could be avoided in MRCs. In order to investigate the feasibility of the proposed material for engineering applications, MRCs were further applied to a magnetorheological fluid brake and a vibration isolator. In the case of fluid brake, the brake torque changeability was provided at a level comparable to the conventional devices. For a vibration isolator, unlike the isolator in which magnetorheological fluid is used, MRC could provide the stiffness change property depending on the magnetic field strength in addition to the damping changeability.
