Topic: Understanding the Dynamics of NASA Deployable Space Structures using Flexible Multibody Dynamics 

Presenter: Brant Ross (EnginSoft USA | MotionPort )

It is critical that deployable space structures, such as solar arrays and antennas, deploy reliably once the spacecraft or satellite is in space. In the past the simulation of large flexible space structures was done as a linear dynamics problem, considering a combination of modal representations of the flexible bodies. But as solar arrays increase in size nonlinear dynamics techniques are increasingly needed in order to consider large displacements in the structures as well as the momentum of the sections of the structure in motion.
