Abstract
A scheme for autonomous control of aerostatic bearing used in large-sized photoelectric precision instrument was proposed. The inherent throttle bearing parameters are optimized according to the maximum stiffness of aerostatic bearing. The carrying capabilities under three active throttle modes of air inlet, air exhaust and air inlet-exhaust are given. The calculation results show that the optimization of bearing parameters is reasonable and can provide a good load range for realizing infinite stiffness for autonomous control bearing. Three active throttle modes also provide variety selection for autonomous control aerostatic bearing.
