摘要
A magnetically suspended vibration isolator with zero stiffness whose angle degree of freedom is decoupled with a joint ball bearing has a main body, in which a sleeve and a lower mounting plate are supported with a magnetically suspended thrust bearing, a piston cylinder and the sleeve are lubricated and supported with a cylinder air bearing surface, and the angle degree of freedom between a upper mounting plate and the lower mounting plate is decoupled with a joint ball bearing; a position close-loop control system comprising voice coil motors, displacement sensors, limit switches, a controller and a driver is introduced, and the relative position between the upper mounting plate and the lower mounting plate is precisely controlled.
