Vibration isolation with quasi-zero stiffness effect

Abstract

The study relates to an important direction of applied mechanics — the theory of vibration isolation of vibroactive objects, such as generators, engines, pumps, compressors, fans, pipelines, etc. The design is proposed, mathematical modeling questions are considered and expressions are obtained for choosing the necessary parameters simple and promising supports using quasi-zero stiffness. It is shown that the proposed support allows to extend towards low frequencies the range of reduction of the force transfer coefficient to the base and thereby improve the vibration isolation of various technological objects
