Abstract

We are developing a shear-type compact MR brake (SCMRB), which can control the share stress because the viscosity of MR fluid varies by the magnetic field and shear rate. In order to design the high response brake, it is important to evaluate the response characteristics by taking into account the non-linearity of stress versus flux density and stress versus rotation speed. This paper presents the response characteristics analysis method of the SCMRB using the 3-D finite element method (FEM). The effectiveness of the analysis is clarified through the comparison with the measured ones. Furthermore, the usefulness of this brake is also clarified through the response characteristics.
