| 摘 要： | 采用保角变换有限元方法计算量纲一的供气孔分布圆半径C、供气孔直径d和供气孔数n对小孔节流盘状静压止推气体轴承静态性能的影响。对承载力特性影响较大的参数是供气孔直径d和供气孔数n,对流量和静刚度特性影响较大的参数是量纲一的供气孔分布圆半径C、供气孔直径d和供气孔数n。按照优先考虑静刚度指标和兼顾流量、承载力指标的设计原则,从分析中得到了一般情况下该类轴承主要几何参数的推荐取值范围。

| Abstract: | Influences of changes of dimensionless orifice distribute circle radius C,orifice number n and orifice diameter d to bearing’s static characteristics were calculated by means of conformal transformation FEM.Variations of orifice diameter d and orifice number n will result in visible influence to static load characteristics of the bearing.Variations of dimensionless orifice distribute circle radius C,orifice number n and orifice diameter d will result in visible influence to flux characteristics and static stiffness characteristics of the bearing.According to design criteria of priority stiffness,considering flux and load,the ranges of reasonable main parameters of the bearing are deduced. |
