Space flexible tether-net is an effective way to capture and remove failed spacecraft and space debris in orbit.In this paper,a towing dynamics model of flexible tether-net entanglement combination is established based on the continuum mechanics,concentrated mass method,and Hertz contact theory,and a simulation analysis is conducted on the towing process.The results show that when an active spacecraft tows a non-spinning target or a spinning target at a 15(°)/s spin speed,the target spin will intensify the entanglement of the tether-net entanglement combination,which may generate new space debris.Adding buffer components between the active spacecraft and target can reduce the peak tension of the towing tether-net,shorten the time of the tether-net combination for forming a stable towing state,reduce the interference with the active spacecraft,and improve the reliability of towing missions.The dynamic simulation analysis can provide reference for the formulation of in-orbit target removal strategies.
