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

摘要

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