Design of the Multi-throttle Air-Lubricated Hydrostatic Slide Guide and Its Stability Analysis

An one-dimension flow model of the multi-throttle air-lubricated hydrostatic slide guide is built in this paper. The bearing capacity and the stiffness of this kind of slide guide can be obtained from the model. Based on the continuity theorem of the air mass variation in the slide guide, dynamic motion equations of the multi-throttle air-lubricated hydrostatic slide guide are also built. Then systematic investigations are made of the parameters involved in order to estimate the stability of the slide guide. So that,theoretical basis for the design of the multi-throttle air-lubricated hydrostatic slide guide is offered in this paper.
