The paper deals with the planar problem of vibration isolation. The active vibration damper is mounted on an oscillating mass with a vibroactive unit at a point that does not coincide with the mass center and the action of the vibroactive force does not coincide with the mass center. An active dynamic vibration damper is an electrodynamic drive in which the translational movement of the moving mass is carried out according to information about acceleration from an accelerometer mounted on an oscillating mass with a vibroactive unit. The paper gives an assessment of the vibration isolation effectiveness, depending on the mismatch with the mass center of the vibrational force application points, the settings of the active damper and accelerometer.
