Abstract

A method is developed to suppress the resonances of the transverse vibrations of the support plate of an active vibration protection device, which makes it possible to expand its active frequency range and reduce the transmission coefficient of vibrations. A second additional control loop is used to control the individual, selected resonances of the plate. Its inertial service thrusters and accelerometers are located on the plate (or in the volume of the plate) in certain positions near the maximum of the wave, and filters tuned to the resonance frequency are installed in the electrical circuits. To describe the structure, a structural diagram is used, consisting of electrical and mechanical impedances, which represent the resonances of the support plate mounted on elastic supports, the resonances of its transverse vibrations, and the resonances in the chain of inertial service thrusters. Application of the theory of electrical circuits makes it possible to determine the dynamic behavior of the control system, as well as the structural and power characteristics of its nodes.
