As a countermeasure for suppressing space debris growth, the Japan Aerospace Exploration Agency (JAXA) is investigating an active space debris removal system that employs highly efficient electrodynamics tether (EDT) technology as its orbital transfer system. In numerical simulation to evaluate the tether’s dynamics, tether has been modeled as point masses connected by linear springs and viscous dampers. However the actual tether shows non-linear behavior. In this paper, non-linear springs model are developed based on the results of dynamic tensile test of the tether. Then numerical simulations are conducted to investigate the effects of non-linearity, especially for the cases when the tether deployment is stopped suddenly
