Abstract

The static performances of the aerostatic guideway are significantly influenced by the fluid-structure interaction (FSI) effect. This paper investigates the FSI process between the air film and two-stage cantilever structure of the slider based on a two-way transient FSI model, in which the thickness and shape of actual air film can be acquired. Moreover, the stiffness of the aerostatic guideway system with two different materials 38CrMoAl nitriding steel and 7075 aluminum alloy, is investigated numerically and compared experimentally. It proves that the structural rigidity of the slider has a non-negligible impact on the stiffness of the aerostatic guideway system. The inner mechanism of this phenomenon is further discussed to provide meaningful guidance for the design of the aerostatic guideway system.
