A new type of multi-microporous stainless steel plate has been developed, and it has a lot of interconnected micropores on its surface and inside. The test results show that the pore size ranges from 0.1 to 15 μm and has regular shape. It is found that the plate has good air permeability by gas permeation test. The porous aerostatic thrust bearing is prepared by using this material, and the test results show that the bearing has high static bearing capacity. In FLUENT, the static characteristics of the porous gas hydrostatic bearing are simulated, and the simulation result is highly consistent with the experimental data, which verifies the correctness of the simulation and provides convenience for the study of the static characteristics of the porous gas hydrostatic bearing. The multi-microporous stainless steel plate can be used in ultra-high speed and ultra-precision instruments such as air lubricated motorized spindle and air bearing guide rail.

基于多微孔不锈钢板的气润滑推力轴承的静态性能研究

已经开发了一种新型的多微孔不锈钢板,其表面和内部具有许多相互连接的微孔。测试结果表明,孔径在0.1至15μm的范围内并且具有规则的形状。通过气体渗透试验发现该板具有良好的透气性。用这种材料制备了多孔空气静力推力轴承,试验结果表明该轴承具有较高的静态承载能力。在FLUENT中对多孔气体静压轴承的静态特性进行了仿真,仿真结果与实验数据高度吻合,验证了仿真的正确性,为研究多孔气体静压轴承的静态特性提供了方便。 。
