Abstract
MR fluid is a functional fluid whose viscosity changes with magnetic field. It has been used for torque transmission mechanisms. But there are few data about its durability. The allowable centrifugal acceleration and expected torque are calculated. Magnetic field analysis was conducted for the development of a durability test apparatus using a permanent magnet. The structure consists of the upper part with a yoke, a doughnut-shaped neodymium magnet, spaces, a disk and MR fluid. The fluid gap has the V shape-type structure in order to arrange MR fluid only in the measurement part.
