Abstract

Miscellaneous active vibration isolation systems designed for laboratory (workshop), transport, and space applications with the decoupled control of six vibration modes of the bearing plate are studied. Using the electric circuit method, a compact mathematical description of the dynamic behavior of individual mechanical and electrical units and of the control of active vibration isolators is obtained. It is shown how, given the basic parameters of a vibration isolation system (the active frequency range and maximal vibration attenuation factor, which are together called efficacy bounds), the parameters of the dynamic blocks of the device and its design characteristics can be determined. The factors that limit the active frequency range and the maximal vibration attenuation factor of vibration isolators are analyzed.
