Abstract
A magnetic silicon rubber membrane is a rubber membrane solidified with a magnetic compound fluid. In this study, vibration properties of a coupled system of a circular magnetic silicon rubber membrane and a magnetic fluid layer in alternating magnetic fields are investigated. Under alternating magnetic field, vibration of the magnetic rubber membrane has phase-delay against the alternating magnetic field. The delay is increasing as the frequency becomes higher. At the range of low frequencies of alternating magnetic field, the amplitude of vibration of the membrane keeps constant value. Vibration properties are different from those of the coupled system of nonmagnetic rubber membrane and magnetic fluid. The coupled system of magnetic rubber membrane and magnetic fluid oscillates sinusoidaly by applying alternating magnetic field.
