摘      要：A study on the dynamic characters and stability of the electrodynamic tether(EDT) system during deploying phase is *** dynamics model of the EDT is established with taken the deformation and tension of tether into *** system’s equilibrium conditions are also derived according to second order linear *** the impact of the gravity gradient torque and the impact of the libration and tension variation of the tether,the stability of attitude of main-satellite under different deployment strategies is ***,series numerical simulations are performed:deployments of uniform velocity and uniform acceleration lead to instability of the main-satellite with its attitude viberated;deployment of power index can resist external disturbance effectively with the attitude of the main-satellite rapid *** what conditions the deformation of the tether could be neglected is calculated,which could provide ideas of control and deploy strategies for the EDT system.
