        Abstract
        Magnetorheological (MR) dampers can
be controlled effectively by magnetic field s . Under the external ma gnetic field s ,
MR fluid behaves as a non Newtonian fluid with controllable viscosity. The response time is a critical factors to determine
its performance. A new MR damper by using foam metal to store MR fluids is proposed . H owever, the response time is a
little different with the traditional ones for the time to extract the MR fluid from metal foam. Therefore, in this paper, t he
delay time , MR fluid was drawn out from the porous metal foam, was investigated in terms of the internal structure
formation by a precise control of external magnetic fields..
