Outline of Final Research Achievements |
In order to solve the sedimentation problem of dispersed particles in the MR fluid in the off-working state, two types of novel MR composites; "MR fluid porous composite" made of nonwoven impregnated with MR fluid and "MR rubber composite (MR elastomer)" consisting of micro-sized iron particles dispersed in a silicone rubber, have been newly fabricated. Exploiting the features and functionalities of two types of the MR composites, a damping-variable seismic MR fluid composite smart damper and a stiffness-variable multilayered MR elastomer isolator with magnetic field have been designed and developed, and applied to semi-active control systems for the seismic isolation and vibration of structures.
