Flux-pinned interfaces maintain a passively stable equilibrium between two spacecraft in close-proximity. Although flux-pinning physics has been studied from a materials-science perspective and at the systems level, the sensitivities and implications of system-level designs on the dynamics need to be better understood, especially in interfaces with multiple magnets and superconductors. These interfaces have highly nonlinear, coupled dynamics that are influenced by physical parameters including strength of magnetic field sources, field-cooled position, and superconductor geometry. Kordyuk’s frozen image model successfully approximates the characteristics of flux pinning dynamics but could provide more precise state prediction with the addition of these physical parameter refinements. This paper addresses that gap by offering parametric terms to improve the dynamics model, which may better simulate the behavior of a multiple-magnet-multiple-superconductor interface. The sensitivity of the general flux-pinned dynamics model is studied by varying the physical parameters and simulating the systems level dynamics. This work represents a critical step in the development of a model suited to spacecraft performance verification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
