| 摘 要： | 针对消除空间旋转目标姿态旋转的问题，本文将第二代高温超导技术与涡流制动技术相结合，提出超导式涡流消旋的概念。然后，对涡流消旋的技术可行性进行了定性分析，通过对多种消旋技术手段的权衡比较归纳出涡流消旋的优势。接着，采用电磁张量理论，建立了电磁-涡流作用机理的精确磁场和涡流力矩模型；最后，考虑实际消旋的任务需求，对典型的高速旋转目标、低速旋转目标、以及复合旋转目标的消旋进行了动力学仿真研究。仿真结果表明，涡流消旋具有足够强大的制动能力，能有效消除目标的高速旋转或复合旋转运动。

| Abstract: | This paper studies the problem of detumbling a non-cooperative space object with a high rotating speed. Firstly, the high temperature superconducting technology and eddy current brake technology are combined together and an eddy brake concept based on superconducting electromagnet is proposed. Then, the qualitative analysis on the technological feasibility of this eddy brake concept is conducted, and the advantages of this combined technology is concluded through the tradeoff analysis among several despin approaches. Furthermore, by applying the electromagnetic tensor theory, the exact magnetic field model and exact eddy current torque model that explicate the action mechanisms of the superconducting eddy brake are derived. Finally, considering the requirement of the practical despin task, the despinning simulation studies of the typical tumbling objects ranging from low speed spin to high speed spin and the objects rotating with nutational motion are performed. The simulation results indicate that the superconducting eddy brake can provide enough brake torque to the despin rotations up to 550 (°)/s or rotations combined with nutational motion. |
