Abstract
This study presents theoretical and experimental investigations of a novel external bypass, fail-safe, magnetorheological fluid (MRF) damper. A fail-safe MRF damper is referred to as a device that retains a minimum required damping capacity in the event of a power supply or electronic system failure. The new MRF device has a simple design, is compact, is capable of generating a considerable dynamic force range, and can be sized for specific vibration control applications. The theoretical formulation is developed based on the Herschel–Bulkley constitutive model for an annular flow. Experimental results are obtained to demonstrate the validity of the theoretical analysis.
