| 摘 要： | 针对人字槽狭缝节流动静压气体轴承，采用SolidWorks软件进行三维建模，采用ICEM软件分区对三维模型进行网格划分，运用ANSYS 环境下的Fluent 软件进行仿真求解。研究了轴承转速n、狭缝类型（连续狭缝与非连续狭缝）、狭缝数m、人字槽数N、偏心率ε等轴承参数对人字槽狭缝节流动静压气体轴承的静态特性的影响规律。结果表明：随着轴承转速的提高，轴承的静态特性提高，非连续狭缝和连续狭缝对人字槽动静压轴承的承载力、静刚度以及耗气量的影响趋势相同；从轴承的承载力、静刚度以及耗气量考虑，非连续狭缝的静态特性优于连续狭缝。当偏心率ε约为0.6，人字槽面积占轴承内壁表面积约为0.1，人字槽个数N为10~12，狭缝段数m为7以及狭缝宽度b1为16~18 μm时，人字槽狭缝节流动静压气体轴承的静态特性最佳。

| Abstract: | For hybrid journal bearings with herringbone slot restrictor, a three dimensional model is developed by the software SolidWorks, and the model is zonally meshed by the software ICEM. The influence of bearing parameters such as bearing speed n, slot types (continuous slot and discontinuous slot), slot number m, herringbone groove number N and eccentricity ratio ε on static characteristics of hybrid journal bearings with herringbone slot restrictor is studied by the software Fluent under the ANSYS environment. The results show that the effects of discontinuous slot and continuous slot on bearing capacity, static stiffness and gas consumption of hybrid journal bearings with herringbone slot restrictor are the same; in consideration of bearing capacity, static stiffness and gas consumption, the static characteristics of discontinuous slot are better than that of continuous slot; the static characteristics of hybrid journal bearings with herringbone slot restrictor are optimum when the eccentricity ratio ε is about 0.6, the herringbone groove area occupies about 0.1 of the inner surface area of the bearing S, the number of herringbone groove N is 10~12, the number of slot m is 7, and the slot width b1 is 16~18 μm. |
