• Magnetorheological fluid (MR fluid)
• Porous foam metal
• Delay time
• Magnetorheological fluid damper

Magnetorheological (MR) dampers can be controlled effectively by magnetic fields. Under the external magnetic fields, 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. However, 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, the 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.
