Webinar: Understanding the Dynamics of NASA Deployable Space Structures using Flexible Multibody Dynamics
Use of Flexible Multipbody Dynamics Software see dramatic reduction in system forces and motion
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.

Who is NASA?
The National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research. Since its establishment, most US space exploration efforts have been led by NASA, including the Apollo Moon landing missions, the Skylab space station, and later the Space Shuttle. NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program which provides oversight of launch operations and countdown management for uncrewed NASA launches.
What is Flexible Mulibody Dynamics?
MFBD (Multi Flexible Body Dynamics) in RecurDyn is a technology to analyze the dynamic behavior of systems which include both rigid bodies and flexible bodies. It is the combination of MBD (Multi-Body Dynamics) analyzing the rigid body motion and the Finite Element Method (FEM) to analyze the motion, stresses, and deformation within flexible bodies. RecurDyn’s solver combines with these two components into a single solver. RecurDyn is much faster and more robust than a co-simulation approach.
