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.
