| 要約: | The magnetorheological (MR) fluid bypass damper fluid flow through a bypass by
utilizing an external channel which allows the controllability of MR fluid in the channel. The
Bypass MR damper (BMRD) contains a rectangular bypass flow channel, current controlled
movable piston shaft arrangement and MR fluid. The static piston coil case is winding by a coil
which is used inside the piston head arrangement. The current controlled coil case provides a
magnetic flux through the BMRD cylinder for controllability. The high strength of alloy steel
materials are used for making piston shaft which allows magnetic flux propagation throughout
the BMRD cylinder. Using the above design materials, a Bypass MR damper is designed and
tested. An excitation of current is applied during the experiment which characterizes the
BMRD controllability. It is shown that the BMRD with external flow channel allows a high
controllable damping force using an excitation current. The experimental result of damping
force-displacement characteristics with current excitation and without current excitation are
compared in this research. The BMRD model is validated by the experimental result at various
frequencies and applied excitation current. |
