Reverse suction air bearing structure

Abstract

The invention provides a reverse suction air bearing structure. The structure comprises an air floatation pad, and a permanent magnet and electromagnets that are arranged on the air floatation pad. Vent holes of the air floatation pad are disposed on the top surface, a concave part is disposed at the center of the air floatation pad top surface, and the permanent magnet is embedded in the concavepart. The reverse suction air bearing structure provided by the invention combines the air flotation technology and electromagnetic technology, during use, the reverse suction air bearing is adsorbedunder a magnetic conductive panel, suspension force is generated by electromagnetic force to achieve balance with the resultant force of an air flotation unit's air flotation force and a hanging load,a hanging point can realize frictionless two-dimensional movement along the bottom of the magnetic conductive panel at the top, and frictionless non-contact free movement in the plane, and the accuracy of microgravity simulation and the system reliability are improved.

Description

technical field [0001] The invention belongs to the field of equipment for simulating microgravity by the suspension method, and in particular relates to a suction-back type air bearing structure. Background technique [0002] Micro-low gravity simulation technology of spacecraft is a new field emerging with the development of space technology, and it is one of the main technologies that all space powers have paid attention to. The microgravity simulation methods include the suspension method, the suspension method commonly used brackets, gantry, swing arm and other structures. The movement of the mechanism creates a large additional disturbance, and the moment of inertia is large, which affects the deployment accuracy. Therefore, in the microgravity simulation method of the suspension method, how to reasonably provide a structure suitable for hoisting has become another research topic. Contents of the invention [0003] In view of this, the present invention aims to prop...
