Abstract
Theoretical and experimental studies are performed for the design, development and testing of a new fail-safe semiactive magneto-rheological fluid (MRF) damper for a high-mobility multi-purpose wheeled vehicle (HMMWV). A fail-safe MRF damper is referred to as a device, which retains a minimum damping capacity required in the event of a power supply or electronic system failure. The proposed MRF damper is designed using a disk shape magneto-rheological (MR) valve. The MR valve occurs in the space between two fixed parallel disks with radial flow. Bingham plastic fluid model and a three-dimensional finite element electro-magentic analysis are employed to theoretically analyze the proposed MRF damper. Experimental and theoretical results are presented for force-displacement and force-time behavior of the damper under different harmonic input motion and various input magnetic fields.
