Abstract: Magnetorheological (MR) damper is a smart device which the damping force can be adjusted according to the working operations in a short time. Metal foam MR damper is a new type of MR dampers in which uses the metal foam to store and release the MR fluids. The dynamic response time of the metal foam MR damper is quite different due to the added metal foam especially for the dynamic response time model. This paper proposed a dynamic response time model for the metal foam MR damper based on the demonstration of the working mechanisms and the factors about the response behaviors.
