In this paper, a new type of vibration isolation mount utilizing magnetorheological fluid (MR mount in short) is proposed. This design is based on two operating modes of MR fluid : flow mode and shear mode. These modes are applied in the design which includes two components: fixed plates for applying the flow mode, and a flexible plate for applying the shear mode of MR fluid motion. These plates belong to the valve-type structure of mount. The primary objective such a MR mount is to overcome the lock-up phenomenon in the conventionaltype MR mount which normally appears at high frequencies with a very small excitation amplitude. The theoretical analysis for the design is undertaken followed by design optimization using ANSYS ADPL software. The objective functions are chosen by maximal damping force of MR mount. It has been shown through computer simulation that the lock-up phenomenon can be avoided and initial requirements with high damping force are successfully achieved by utilizing the proposed MR mount.
