摘要：

阐明了空气静压轴承的层流模型结构及原理,介绍了多孔质空气轴承具有易于实现流体层流的特点,并提出了仿真模型。试验证实，通过多孔质结构使流体成为层流是一种重要的抑制微振动的方法，它可以将运动部件的振幅控制在0.6nm内，并使金刚石刀具切削的大尺寸无氧铜工件表面的粗糙度Ra提高到1.3nm。

Abstract:

An effective way of suppress micro-vibration caused by air bearing is keeping the air flow in laminar state. Porous air bearing was proposed and tested

herein to optimize the flow state. The mold structure of the porous bearing and the principle of its function were also proposed. It is verified that after laminarization of the air flow in porous bearing, the micro-vibration of the moving parts of a machine tool can be controlled to 0.6nm, and the roughness of the diamond-cutting surface of large OFC(oxyacid free copper) workpiece can be improved to 1.3nm.
