CONTACT-IMPACT OF SOLAR BATTERY DURING THE DEPLOYMENT OF THE PLATES
摘要
Abstract
In this paper, the contact-impact problem of solarbattery during the deployment of plates is studied. The equation ofmotion of flexible multibody system during impact is derived. The timehistories of impact forces and the acceleration of some nodes of theplates are presented. It shows that the impact forces of the contactpoints reach the peak at different time on account of the distortion ofthe flexible plates. It also shows that when impact occurs, theacceleration of the nodes near the impact points are greater than thatof the other nodes, and it takes few time for the impact wave to spreadthrough the flexible plates. When the impact wave reaches the nodes atthe boundary of the outer plate, the acceleration of the nodes becomesgreater and vibrant which leads to the swinging of the plates.关键词
