The inertial compensation of the vibroactive force in the oscillating system

Abstract

Actuators used in active vibration isolation systems of various types are either installed between the oscillating mass and the base, or next to the elastic-dissipative elements of a passive system. The actuator is usually controlled according to information from force-measuring devices. This significantly complicates the implementation of such systems. An active system is considered in which an electrodynamic drive (actuator) is used to compensate for vibroactive forces transmitted to the base. An electrodynamic drive is mounted on the base and controlled by accelerometers mounted on the passive system moving masses and the actuator. Straight-line controlled vibrations of the actuator moving mass provide inertial compensation of vibroactive forces on the base.
