Vibration Properties of a Coupled System of a Magnetic Fluid Layer and a Magnetic Rubber Membrane

摘要

Vibration properties of a coupled system of a magnetic fluid layer and a magnetic rubber membrane that is a silicon rubber membrane containing a magnetic compound fluid are investigated experimentally. Displacement of the membrane is measured when an impulsive magnetic field or an alternating magnetic field is applied to the system. The maximum displacement at the central point of a circular membrane and time variations of displacement are shown.
