The research of space net control strategy based on the combination of fixed tearing belt and tether brake

Abstract

In order to solve the rebound motion of space tether net during deployment, a new control strategy based on adding tear tape in the plane and applying tether force out of the plane is proposed. The tether segment of the space tether net is discretized, and the lumped mass model is established. According to the mechanical characteristics of the tether, the system dynamic equation is derived. Then the simulation analysis is made from the perspective of evaluating the effect of the control strategy. Through simulation and comparison, it is found that the control strategy has obvious effect on restraining the rebound movement of the tether net.
