Experimental Investigation of Multiple Coils Magnetorheological Damper under Dynamic Loadings

Abstract:

This paper presents performance comparison of Magnetorheological (MR) damper with two different coil arrangements. Two coils at different location have been introduced that could enhance the activation areas in the MR damper. The experimental tests were conducted in three different conditions of coil; internal coils, external coils and the combination of coils. For each trial, the effect of the applied current and the condition of coils were analyzed and investigated. The results showed that the internal coil could produce higher damping force than the external coil, and the combination of internal and external coils could increase the damping force up to 125 N for the same experimental parameters.
