摘要

摘要: 为了分析轴承的加工工艺和径向间隙对轴承静态、动态性能的影响，设计搭建了静态、动态实验台，利用改变轴颈尺寸的方法研究不同径向间隙对气体箔片轴承（GFB）静态性能和动态性能的影响，还分别研究了不同波箔弹性结构、不同箔片材料和不同波箔热处理方式等因素对轴承性能的影响.结果表明：随着径向间隙减小，气体箔片轴承静刚度及其动态结构刚度增大，其等效黏性阻尼随着径向间隙的减小，出现先增大后减小的趋势.在工艺上箔片材料及波箔弹性结构对轴承性能的影响起重要作用.

Abstract: In order to analyze the static stiffness, structure stiffness and viscous damping of bearing under different factors, the experiment rigs for gas foil bearing (GFB) static and dynamic characteristic experiment were established. By changing the size of the journal of a same bearing, the influences of radial clearance on the static and dynamic properties of experiment bearings were studied. Additionally, the different bump foils, foil materials, ways of heat treatment and other factors affecting bearing elastic structure properties were also investigated. Result shows that, with the decreasing radial clearance of the bearing, the static stiffness and dynamic structure stiffness increase gradually and equivalent viscous damping increases first and then decreases; different bump foils and foil materials play a major role in GFBs' structural properties.
