In order to prove the possibility, a series of tests was performed using a direct-made experimental setup which contains a metal plate, springs and varying dampers. The frequency of the harmonic force variation and damper variation was set as f1 and f2. The plate center displacement achieves a peak point in the frequency component f1 and the rotational displacement achieves a peak point in the frequency components f1 + f2 and f1 − f2. In the experiment, the damper variation changed due to the damping constant value and current magnitude. Meanwhile, research on the natural frequency of the rotational displacement will continue. The inference of the reason for absence of frequency component related to rotational displacement natural frequency fnr is that the MR damper shows non-linear phenomenon in this experiment.
