    Abstract
  • The magneto-elastic buckling problem is a hot topic of Electrodynamic Tether (EDT) system because of its strongly nonlinear dynamics and the existence of complicated multi-fields coupling problems. An elastic rod model for EDT is established based on the geometrically exact Kirchhoff equations, and the effect of geomagnetic environment on EDT is analyzed. The static and dynamic instability of EDT are thoroughly studied, and the critical value of magnetic field as the bifurcation happens is calculated. The results show that the critical value decreases as the angular velocity increases, which can provide a reference for the current and other parameters design of EDT.
