FORCE-FEEDBACK DEVICE USING MAGNETORHEOLOGICAL FLUID : MR CLUTCH

Abstract

As one of power transmission devices, a clutch transmits a power from power source to operating parts. Most of clutches are susceptible to damages by backward power transmission. To cope with this problem, we investigate a new type of clutch which uses magneto-rheological fluid (MRF). This MR clutch has a simple structure, and can control the transmitting power and avoid power source breakdown by excessive backward power transmission. Since the MR clutch can act as semi-active damper as well, we can apply this device to various fields that need clutch and damper at the same time. In order to confirm its performance and investigate its applicability, we designed and manufactured MR clutch, and applied it to build a force-feedback device for virtual bicycle simulator.
