Vibration properties of a coupled system of a magnetic fluid layer and a magnetic rubber membrane

Abstract

Vibration properties of a coupled system of a magnetic fluid layer and a magnetic rubber membrane which is a silicon rubber membrane containing a magnetic compound fluid are investigated experimentally. Under alternating magnetic field, vibration of the coupled system has phase lag against the field, and the lag increases as the frequency becomes higher. At the range of low frequencies of the field, vibration of the system keeps nearly constant amplitude.
