Abstract
A method of designing a new bearing system is presented. The finite difference computation model of the elastic membrane is established. The coupling computation process is designed for the computation model of the aerostatic bearing with pressure groove and the finite difference computation model of the elastic membrane. The iterative process to solve the fourth-order partial differential equations (elastic membrane deformed governing equation) is explored successfully with the multi-grid method. The experimental results show, the width and depth of annular membrane of the bearing changes with the designed air pressure to meet the control requirements. The results indicate that the design, machining and test of the new structure are satisfactory and successful.
