Abstract

The invention discloses a space mechanism ground gravity compensation method. The space mechanism ground gravity compensation method comprises the following steps: (1) gravity compensation of equipment, (2) adjustment of rotating shaft superposition, (3) gravity compensation of a product, (4) adjustment of a pretension force of a suspension rod of the product, and (5) space mechanism ground simulation. The problem of ground weightless simulation of a large mechanism of a certain type space station can be solved effectively. Functions of gravity compensation, posture alignment, positioning and the like are fulfilled.

Description

technical field [0001] The invention relates to a gravity compensation method, in particular to a ground gravity compensation method for an aerospace space mechanism. Background technique [0002] The space station is a long-term operation in low-earth orbit, representing the most comprehensive, complex, advanced and comprehensive technological level in today's aerospace field. The field plays an important role that cannot be replaced by other spacecraft. The solar wing is an array of multiple solar panels that converts solar energy into electrical energy for use by satellites in space orbit. From the launch of the spacecraft to the orbit, the solar cell array goes through the stages of folding, unlocking, unfolding, and locking in sequence. Due to the important task of providing energy for satellites, whether the solar wings can be successfully launched and work normally after launch directly affects the success or failure of satellite launches. [0003] In the history o...
