Dynamic Characteristics Analysis Of Water Lubricated Rubber Alloy Bearing

Water lubricated rubber alloy bearing is one kind of special bearing, which can suppress the vibration, reduce noise, and have wear-resisting property, for the use of water as a lubricant and the special physical and chemical properties of rubber, it has good lubricating properties with the unique advantages of resource saving and environment-friendly property, and it is widely used in the underwater environment. People have pay more and more attention to the innovative design theory, methods and technology, with the oil,precious metal prices goes up and the deteriorating of the environment. By the study the dynamics characteristic of the bearing, including the vibration and noise analysis, we can master the influence the bearing structure and material parameters on the quality of its working, which has important theoretical and practical value. Haven read many important documents on this kind of bearing, the author used finite element analysis software to analyze the vibration and noise of the bearing, and have pointed out the methods for vibration and noise reduction.①Introduced the study of water lubricated rubber alloy bearing status and development trend, from shell theory of Reddy, the vibration control equation of the bearing has been derived, which have provides a theoretical basis for the bearing vibration analysis.②The three-dimensional geometric model and finite element model of the bearing have been constructed, based on the modal shape, the influence of the bearing copper shell and inner rubber on the Modal shape are discussed.③The steady dynamic response and transient response of the bearing are analyzed, by the analysis of the shell copper the inner rubber and the combined layer respectively, the characters of the bearing response are discovered.④By changing the bearing material and structural parameters ,the bearing steady-state response and transient response have been attained , by which the vibration reduction measures has been proposed.⑤Using complex eigenvalue theory ,The influence of the structure of the bearing is studied, and the noise reduction measures have been proposed.This research is funded by the State Natural Sciences Foundation General Projects:"Innovative design theory and method of water lubricated bearing system with large size and high specific pressure(Number:50775230).The paper will provide a reference for study the noise and vibration of water lubricated rubber alloy bearing.
