- Abstract
The deployment and locking process of solar wings of the free-floating spacecrafts was studied. The dynamic model describing the deployment and locking process was established with the method of forward recursive formulation. The contribution of joint friction to the dynamic equations was derived based on the virtual power principle. The closed dynamic equations for the system was constructed through supplementation of the dynamic balance equations for the bodies with the frictional joints' effects. The validity of the proposed model was verified through comparison of the simulation results with those of the ADAMS software. Research results show that the proposed model effectively describes the deployment and locking process of solar wings, the joint friction has considerable influence on the dynamic behavior of the mutibody system, and the PD control method substantially restrain the drift of the spacecraft attitude caused by the deployment of solar wings.
