| 20110120207 | METHOD AND DEVICE FOR CHARACTERIZING MAGNETORHEOLOGICAL FLUIDS - A method for characterizing magnetorheological fluids using a volume flow rate measurement. The volume flow of the magnetorheological fluid through a capillary is initially measured, with a constant weight force being applied onto the magnetorheological fluid. A magnetic field is then applied to the capillary, and the volume flow of the magnetorheological fluid through the capillary is measured with the magnetic field applied, with a second constant weight force being applied onto the magnetorheological fluid. A device for carrying out the method comprises a container for storing a magnetorheological fluid, wherein the container is connected on one side to a capillary through which the magnetorheological fluid can flow, and is closed on a different side by a movable piston, which presses the magnetorheological fluid through the capillary with a constant weight force, and means for generating a magnetic field are provided in the region of the capillary. | 05-26-2011 |
