Paper Abstract

This study focuses on the performance of a magneto-rheological (MR) grease damper. MRGs consist of micron-sized ferrous particles suspended in a grease carrier material. The main advantage of a MRG over a MR fluid is that in a MRG ferrous particles do not settle. Experiments are conducted to measure the output force response of the damper under various sinusoidal motion input conditions. The performance test consists of a sinusoidal frequency sweep maintaining amplitude at a constant displacement. In each test, the input electric current applied to the prototype MRG damper is kept at a constant level of 0, 1.0 and 2.0 Amps. Results demonstrated that a controllable damping force can be achieved which at low frequencies damper is nearly twice of the passive damping force.
