High Stiffness High Damping Structure
Abstract
This effort was an investigation on the preparation of a novel smart structure with tunable damping and stiffness properties. This structure was a Magneto-rheological (MR) fluid filled volumetrically stiff cylinder. The MR fluid contained magnetic particles with various particle sizes ranging from nanometers (15-20 nm) to several microns (45 microns). An application of an external magnetic field would then alter the rheology of the MR fluid thereby resulting in variation in stiffness and damping properties of the cylinder. Fluids were prepared with various amounts of solids loading and filled in a tube. The behavior of the struts containing a mixture of nano and micron sized iron powders were strongly influenced by the weight fraction of the large particles.
