自补偿液体静压轴承静/动态特性有限元分析
FEM Analysis of the Static and Dynamic Characteristics of Self-compensating Hydrostatic Bearing
摘要
Abstract
Theoretical and experimental studies were carried out on a new type of self-compensating bi-conic hydrostatic bearing.The structure and operating principle of self-compensating bi-conic hydrostatic bearing was introduced.Theoretical models of the lubrication film were built with perturbation method, and the influence of rotor motion on the restrictor gap was taken into account for the self-compensation re-stricting equation.The model was solved in finite element method (FEM)and was validated with experi-ments.Load carrying capacity,fluid flow rate,stiffness and damping coefficients were studied.The re-sults have shown that the self-compensating hydrostatic bearing has higher radial load carrying capacity than fixed-slot compensating bearing under the same condition,and it has high stiffness coefficients when used under low load.关键词
