Dynamic Simulation of Multifold Deployable Rings

摘要

This Note extends previous studies on deployable elastic rings by proposing the concept of multifold buckled rings and addressing a potential application of them to the foldable and deployable flat-mesh reflector. Dynamic deployment of a satellite system with a 12 m flat-mesh reflector is investigated using multibody system dynamic simulation. The axial and bending stresses in the elastic ring during the deployment are analyzed. With the advancements in materials and manufacture technologies, multifold buckled rings will be applied to large/huge space deployable structures.
