Development and application of lifting and levelling system for space station

Abstract In this paper, the characteristics of the hoisting assembly process of the space station are analysed. The adjusting parameters of suspension under different eccentric conditions are explored. The scheme of the hoisting levelling system during the hoisting process of the space station is put forward, and various levelling means are given. Through collecting and analysing the geometric parameters of the distance from the horizontal plane during the hoisting process, the relative position and posture of the space station and the horizontal plane under the current state are obtained. Through theoretical calculation and analysis model, the levelling control software is compiled, and the automatic levelling of the space station is realized. The feasibility and accuracy of the design scheme are verified by laboratory results and actual levelling analysis. The controllability, stability, convenience and safety of the space station hoisting operation are improved.
