| Aerospace industry is a key domain spported by gavernment,and is also the strategicindustry in the21st century. As a systematic project,it need meticulous planning. Due tothe limitation of rocketry, large-scale spacecraft are mainly modular designed andassembled in the space after launched. Compaerd to the conventional kinematicconnection, a novel connecting method based on flux pinning effect has provided a newidea for on-orbit assembly. Under the support of NFSC, we are able to carry out a studyon the possibility of flux pinning effect applying to spacecraft docking process. Themajor work of this dissertation includes:We have analyzed theoratically the feasibility of frozen-in model applying to radicalmovement and simulated the properties of PM-HTSC pair in radical movement includingthe tendency of the force and factors that contributes to the change of the force. With thehelp of MATLAB, we have also alalyzed time response of the structure under fluxpinning force and damping.We also analyzed the force experimentally, confirming the feasibility of simulationobtained last chapter, and redefined the flux pinning coefficient of the superconductors infield colling condition. Meanwhile, hysteresis effect n such situation are studied. In theend, we briefly explained the design of the platfrom.We studied the relationship between tangential force and angles, and many otherfactors that may affect the force. Also studied are the feasibility of the PM-HTSC pairusing for damping system and confirmation of it by experiment.In the4th part, we conjugate the HTSC by electromagnet, to make it a driving forcrresources and experimented the repulsive force in field cooling condition.The research above indicate: the tangential force is in contrast to the movingdirection in field cooling condition to make it has the potential to be damping system. Inzero field cooling condition, the repulsive force was great enough for use when reversethe field direction. |
