Conical metal-rubber support with quasi-zero stiffness effect

The study relates to the important branch of applied mechanics - the theory of vibration isolation of vibroactive objects such as generators, motors, pumps, compressors, fans, pipelines, etc. The design and mathematic model of a prospective support structure using quasi- zero stiffness effect were considered. The support consists of an elastomeric shock reducer as a shell in cross section having a truncated cone shape with inserted cylindrical elastomer spring, specially selected thanks to its elastic characteristics and size, to obtain characteristics with quasi- zero stiffness near support equilibrium. The mathematical model of the support, allowing to select options to reduce the factor of the force transmission to the base in a certain frequency range was obtained. The calculations for the model and charts show the efficiency of vibration isolation for the proposed support.
