Introduction Hysteretic models Identification methodology Future work Experimental identification Summary Diagram of the identification experiment layout MR damper fixed on top of the Shake Table. The sensors used are: (i) a load cell, (ii) laser displacement, and (iii) accelerometer. Arturo Rodríguez Tsouroukdissian Small-scale MR dampers for vibration mitigation
Introduction Hysteretic models Identification methodology Future work Experimental identification Summary Identification of a small-scale MR controllable-friction damper tests Experimental input current From the shear-mode MR damper model, the modified Dahl model has to include the voltage as k x(v) = k xa + k xb v k w(v) = k wa + k wb v ˙v = −η(v − u) η = positive constant, u = command voltage applied to the Wonder Box, and v = is a varying voltage. η can be determined if u is available as the system is linear. Loading experiments using constant and variable input current using a convex input signal in its loading part. Arturo Rodríguez Tsouroukdissian Small-scale MR dampers for vibration mitigation
