Application of electro-rheological fluids to flexible mount and damper devices

This article introduces two applications of electro-rheological fluid (ERF), an ERF rubber flexible mounting element and an ERF damper, in order to suppress the vibration of machine elements. Both of them are manufactured and the results of their basic performance measurements confirm that the compliance and the damping of them can be changed according to the intensity of applied electric field. Also three ERF mounts applied to the supporting elements of a table make the resonance frequency of the table changeable. Furthermore the ERF damper applied into a tool shank increases the accuracy of cutting process.
