Assembly process of spacecraft

Abstract

The invention provides an assembly process of a spacecraft, and belongs to the technical field of spacecraft production and assembly. The technical problem that an existing spacecraft assembling process is low in efficiency is solved. The process comprises the following steps of cabin plate split charging, wherein functional elements are fixedly installed on a + Z cabin plate, a-Z cabin plate, a + X partition plate, a-X partition plate, a + X cabin plate, a-X cabin plate, a + Y cabin plate and a-Y cabin plate correspondingly; assembly before testing: wherein the-Z cabin plate, the + X partition plate, the-X partition plate, the + Z cabin plate, the + X cabin plate and the-X cabin plate are sequentially spliced and spliced through connecting pieces; a normal-pressure thermal cycle test: under a normal-pressure condition, the spacecraft which is assembled before testing is exposed to a preset high-low temperature alternating test environment for testing; and cabin sealing and assembling: the + Y cabin plate and the-Y cabin plate to the spacecraft subjected to the normal-pressure thermal cycle test are assembled by a connecting piece. According to the assembly process of the spacecraft, the assembly quality of the spacecraft can be guaranteed while the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft production and assembly, and relates to a spacecraft assembly process. Background technique [0002] An artificial earth satellite refers to an unmanned spacecraft that orbits the earth and orbits more than one circle, referred to as an artificial satellite. An artificial satellite is the most widely launched, most widely used, and fastest-growing spacecraft, mainly used for scientific exploration and research. , weather forecast, land resource survey, land use, regional planning, communication, tracking, navigation and other fields. At present, most micro-satellites adopt a deck structure, including solar wings, several decks and functional components installed on each deck. The entire process of assembling several decks to form a box structure is an assembly process, and the control and optimization of this process play an important role in the quality assurance of spacecraft products.

Problems solved by technology

[0004]However, the thermal cycle test in the above scheme needs to be carried out after the spacecraft is assembled, the test preparation is long, and the abnormal test results need to be disassembled throughout the satellite, which is inefficient and will affect the quality of reloading
