CONTACT-IMPAC OF SOLAR BATTERY DURING THE DEPLOYMENT OF THE PLATES

In this paper, the contact-impact problem of solar battery during the deployment of plates is studied. The equation of motion of flexible multibody systemduring impact is derived. The time histories of impact forces and the accelerationof some nodes of the plates are presented. It shows that the impact forces of thecontact points reach the peak at different time on account of the distortion of theflexible plates. It also shows that when impact occurs, the acceleration of the nodesnear the impact points airs greater than that of the other nodes, and it takes fewtime for the impact wave to spread through the nexible plates. when the impactwave reaches the nodes at the boundary of the outer plate, the acceleration of thenodes becomes greater and vibrant which leads to the swinging of the plates.
