Design and Capability Analysis of a Generalized Electromagnetic Capture Device for Microsatellites

Aiming at the requirements of regular on-orbit release and docking of microsatellites, this paper optimizes a generalized electromagnetic capture device and carries out its capability analysis, which preliminarily solves the problems of the design and capability envelope analysis of the magnetically controlled capture device. Firstly, the magnetic control requirements of microsatellite docking are analyzed, and then the design principle, structural composition and working mechanism of the electromagnetic capture device are elaborated. Secondly, the magnetic capture device is optimized and simulation analysis is carried out based on Ansys Maxwell software to systematically evaluate the capture capability of the device, which mainly includes the capabilities of long-range capture, self-docking and flexible docking. Finally, the application prospect of the magnetic capture device is outlooked, and further research directions are proposed.
