The paper presents a new disk-type porous foam metal magneto-rheological fluid actuator and investigates the shear performance experimentally. The actuator has the following characteristics, MR fluid is stored in porous foam metal, in action of magnetic field, MR fluid will be extracted out from the porous foam metal and fill up the shearing gap, and produce the MR effect. The influence of the materials with different relative permeability, the current, the shear rate and the gap on the shear performance are investigated and analyzed experimentally. The experimental results show the volume of MR fluid extracted from porous foam metals is one of the critical factors for the shear torque of the actuator. Last, to validate the effect of volume on the shear torque, the experiment is studied by adding the different volume of MR fluid on the gap.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
