Abstract: |
Combined with the development trajectory and product characteristics of the step-by-step deployment solar wing, the ground zero gravity test technology of the step-by-step deployment solar wing is studied, and the overall scheme of the zero gravity deployment test technology is designed. Considering the long trajectory of the outer plate, a set of L-shaped transverse guides with anti-jamming function is designed, which solves the problems of twisting and jamming of the transverse guides during the deployment of the solar wing. Aiming at the problem of large frictional force of outer transverse guide, a set of pulley assembly is studied to effectively reduce the frictional force during the deployment of solar wing. In this paper, the assembly technology of step-by-step deployable solar wing and the ground deployment test technology of solar wing are studied. The results show that the deployment, locking and other test parameters of distributed deployed solar wings on the ground can be validated effectively by this method. |
