Paper Abstract

This paper presents experimental results for a novel external by-pass, fail-safe, magneto-rheological fluid (MRF) damper. A fail-safe MRF damper is referred to as a device which 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, can generate a considerable dynamic force range, and can be sized for specific vibration control applications. As an example of the performance of this by-pass valve, a MRF damper is presented that can be used for vibration mitigation in cable stay bridges under strong storms. Performance characteristics of the by-pass valve and the MRF damper are discussed.
