| Abstract: | Conventional aerostatic bearings have the problems of vibrations and motion inaccuracy due to the low stiffness. To overcome these problems, authors propose a control scheme of active control acrostatic bearing. This new type of bearing is composed of noncontact sensors to detect the radial displacement of its axis, control valve to drive the axis and a controller to regulate the whole system. When radial load is applied, the active bearing can surpress the displacement of the shaft,thus obtaining an infinite stiffness. Three kinds of control ways are presented, and corresponding numerical values of infinite stiffness are given. |
