Experimental Study on Performance Characteristics of Magnetorheological Damper
MR dampers are new kind of the most promising devices for structural vibration control. In this paper, an overview of the structure and working principle of shear-valve mode magnetorheological (MR) damper is given. An experimental study was carried out to test the performance characteristics of a shear-valve mode MR damper, its dynamic testing was performed on a Material Testing System (MTS) under sinusoidal and triangle excitation. Based on experimental data, the dynamic characteristics, energy dissipation and dynamic response time were analyzed. The present work lays down a foundation for MR damper application in the semi-active vibration control system.
