FIGURE 4.68 Photograph of one of the DDs used
in our experiments.
FIGURE 4.69 Layout of an active damper. Force P changes
depending upon the free vibrations of the mass m.
FIGURE 4.70 Oscillation amplitude versus frequency of P and
time during the first 5 seconds. A "valley" of almost zero
amplitudes at freo^iency about co = 18 I/sec is clearly seen.
