由于太空中的失重环境,大型空间在轨装置的对接与组装面临着一系列的技术难题,自适应对接结构及技术被视为是解决这些难题的重要途径.基于高温超导体的磁通俘获,超导体磁通钉扎为自适应方式提供了一种新型的非接触对接组装途径.论文提出了一种将高温超导体应用于空间对接的基本方案,并结合该方案展开了超导体励磁和对接力学特性的基础实验研究.研究表明,超导体钉扎效应受励磁过程影响显著,小尺寸的常规电磁场励磁很难促使强钉扎特性;励磁场作用于对接过程的方式对电磁对接力的影响很大,依赖励磁场和超导体的共同作用,对接力在轴线方向上表现出显著的自稳定约束特性.
Due to the weightlessness environment in space, docking and assembly of large-scale on-orbit devices are faced with a series of technical problems, and adaptive docking structures and technologies are considered as important ways to solve these problems.Fulk-trapping based on high-temperature superconductors, superconductors Flux pinning provides a new way of non-contact butt-joint assembly for adaptive mode.The paper presents a basic scheme of applying high-temperature superconductor in space docking and unifies the scheme to lay the foundation of the excitation and docking mechanical properties of superconductors Experimental results show that the pinning effect of superconductor is significantly affected by the excitation process and the small size of conventional electromagnetic field excitation is hard to promote the strong pinning characteristics.The way that the excitation field acts on the docking process greatly influences the electromagnetic relay force, And superconductor interaction, docking force in the axial direction showed significant self-stability constraints.
