Reconfigurable Mechanism for Space Tethered Formation Flight

Abstract

The invention discloses a recombination mechanism for space rope system formation flight. The recombination mechanism is composed of four sub-mechanisms with the same structure; each sub-mechanism comprises a catapult-abut joint part and a tied rope control part; each catapult-abut joint part comprises a cone cylinder, four springs, four guide rail rods, four guide rail cylinders, a cone rod and a shell; each tied rope control part comprises a tied rope, an encoder, an electromagnetic brake, a servo motor, a tension sensor, a reducer, two bearing seats, a rope winding cylinder, an auxiliary guide wheel, a tension measuring wheel, a rope length measuring wheel, a tension preloader, a rope walking plate, a bottom plate and a rope length encoder; and one ends of the tied ropes enter through the centers of the cone cylinders from the shells, pass through the tension preloaders, the rope length measuring wheels, the tension measuring wheels and the auxiliary guide wheels, and then are fixed on the rope winding cylinders, and the other ends of the tied ropes are connected with the middles of the cone rods of the adjacent sub-mechanism. The recombination mechanism can improve the reliability of rope system formation flight and reduce control complexity.

Description

technical field [0001] The invention relates to tether formation flight, in particular to a reconfigurable mechanism for space tether formation flight. Background technique [0002] Spacecraft tethered formation flight maintains or controls the formation configuration by controlling the tension of the tethers between spacecraft, which is a relatively new field formed in the past two or three decades. Although the research on tethered formation flight started relatively late, its great application value and prospects in space interferometry, space imaging, and on-orbit capture have been widely recognized by people. The traditional implementation of multi-spacecraft formation flight is to maintain the formation formation by jet force control, which consumes a lot of fuel in the process of formation control. In order to solve the fuel consumption problem of traditional spacecraft formation flight, researchers have proposed a variety of spacecraft formation flight schemes, such...

However, the multi-tether structure also makes the dynamic structure of the formation system more complex, and puts forward higher requirements for the synchronization control capability and fuel consumption of space vehicles.
