Unstressed installation method for solar cell array driving mechanism

Abstract

The invention relates to the field of spacecrafts and aims to provide an unstressed installation method, which solves the problems of unstressed butt joint between a solar cell array and a driving mechanism and the like. The method is characterized in that: the flatness of an installation surface and the horizontality or the perpendicularity of a reference axis are ensured by a solar cell array driving mechanism installation plate [1]; the spatial position of a solar cell array driving mechanism product [2] on a corresponding installation plate is ensured through a solar cell array driving mechanism simulation tool [3] of which the appearance is similar to that of the product and the accuracy is improved, and the reset accuracy of the product is ensured through a positioning block [4]; a solar cell array installation frame [5] is adjusted or machined on the basis of the spatial position of the high-accuracy solar cell array driving mechanism simulation tool [3] which is determined in a spacecraft; and a solar cell array [6] in an unfolding state is in unstressed butt connection with the solar cell array driving mechanism [2] by measures such as integral translation, rotation and the like. The invention has the advantages that: the method is reasonable, simple and convenient, is practicably operated, makes installation reliable, has high adaptability, and the like.

Description

technical field [0001] The invention relates to an installation method of a solar battery array driving mechanism used in spacecraft such as satellites. Background technique [0002] The solar cell array driving mechanism is the rotating interface between the spacecraft structure and the solar cell array, and is the executive mechanism of the sun-oriented control system of the solar cell array. The driving mechanism receives the driving control signal provided by the driver, and drives the solar cell array to rotate, so that the front of the solar cell array (attached to the solar cell sheet) is always perpendicular to the sun's rays, so as to obtain as much solar energy as possible and provide electrical energy for the spacecraft; The electric power emitted by the battery array and the electrical signal measured on the battery array are transmitted to the interior of the cabin through the conductive slip ring of the drive mechanism. Therefore, in the development process of...
