<p>A fluid-filled active vibration damping device for actively damping a vibration of a desired object (124), wherein an elastically deformable elastic body (16; 146) and an oscillating body (48; 132) partially define a fluid chamber (54, 56; 100; 138, 154) filled with a non-compressible fluid, and the oscillating body is elastically supported by an elastic support member (50; 132) such that the oscillating body is oscillatable by an actuator (66, 68, 82; 102, 104, 105, 110, 112; 136, 160), so as to control a pressure of the non-compressible fluid in the fluid chamber, and wherein a control device (94; 162) controls the actuator by applying thereto a pulse signal whose frequency corresponds to a frequency F of the vibration of the desired object (124), and the oscillating body (48; 132) has a natural frequency fa which satisfies an inequality, (1/ 2ROOT 2)F < fa < 2F. <IMAGE></p> |
