Summary<br />
Identification of a small-<strong>scale</strong> MR controllable-friction damper tests<br />
Experimental input current<br />
From the shear-mode MR damper model, the modified Dahl model has to include the voltage as<br />
k x(v) = k xa + k xb v<br />
k w(v) = k wa + k wb v<br />
˙v = −η(v − u)<br />
η = positive constant, u = command voltage applied to the Wonder Box, and v = is a varying<br />
voltage. η can be determined if u is available as the system is linear.<br />
Loading experiments using constant and variable input current using a convex input signal in its<br />
loading part.<br />
