4.7 Electrically Controlled Vibration Dampers 169
It can be seen in Figure 4.71 that the cross sections of the surface given in Figure
4.70 produced at different times have a minimal value of oscillation amplitudes at a
certain value of the frequency of the applied force P(t).
The force generator proposed in this case is an electromagnet fastened to the vibrat-
ing mass M (say, the arm of the robot). The magnet consists of a core 2, a coil 3, and
an armature 4. An elastic layer (not shown in Figure 4.71) is placed between 3 and 4.
When energized, the magnet develops a force P, pulling the armature. As a result, a
