| Outline of Final Research Achievements |
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.
