| Research Abstract |
Adding fibrous material to a magnetic compound fluid is effective on increasing damping force of a damper. Viscous property of a magnetic functional fluid can be changed by applying magnetic field when needle-like magnetic particles are contained in the fluid. We have found that the damping force becomes stronger when the working magnetic compound fluid contains little amount of magnetic fluid with needle-like magnetic particles.
The damping force of a damper using a magnetic particle assemblage increases in the presence of magnetic field and the damping force rapidly increases near the dead centers. The damping propery of the damper using a particle assemblage depends on the setting angle of the damper. Applying magnetic fied by two magnets arranged near the edge of the damper is useful method to suppress the dependency of damping force on the setting angle of the damper.
