Air floatation hanging type gravity unloading device for space deployable mechanism

Abstract

The invention relates to an air floatation hanging type gravity unloading device for a space deployable mechanism. A first longitudinal guide rail and a second longitudinal guide rail are located on the same horizontal plane and are parallel to each other; the first lateral air floating block is mounted on the outer side surface of the first longitudinal guide rail, and the first upper air floating block is mounted on the upper side surface of the first longitudinal guide rail; the first lateral air floating block and the first upper side air floating block are fixedly connected with one end of the transverse guide rail through a bracket; the second lateral air floating block and the second upper air floating block are fixedly connected with the other end of the transverse guide rail through a bracket; the lateral air floating block, the upper air floating block and the transverse air floating block are suspended by compressed air; the lateral air floating block and the upper air floating block move on the longitudinal guide rail, the transverse air floating block moves on the transverse guide rail, the target mechanism is connected with the transverse air floating block, and the two-dimensional movement of the target mechanism in a plane is simulated through the longitudinal movement of the lateral air floating block and the upper air floating block and the transverse movementof the transverse air floating block.

Description

technical field [0001] The invention relates to an air-floating hanging gravity unloading device for a space expandable mechanism, which can realize the two-dimensional movement of the expandable mechanism under the condition of low damping, and belongs to the microgravity simulation technology for the ground assembly and adjustment test of the spacecraft mechanism field. Background technique [0002] As the size of the part of the deployment mechanism required by the space deployment mechanism becomes larger and larger, the weight also becomes larger. For example, some high-power solar wings can reach 20m in length after deployment, and a single solar panel weighs 30kg. Some antennas The weight of the single board is 50-200kg. These weight changes bring new difficulties to the ground simulation of the microgravity environment, because the frictional resistance of traditional mechanical bearings increases significantly under heavy loads, which can no longer meet the ground d...
