Abstract [en]

The rapidly growing use of nano- and pico-satellites for space missions requires deployable systems to be highly storable yet large and with adequate mechanical properties when deployed. This paper focuses on the modeling and simulation of a meter-class passively deployable boom - based on the SIMPLE boom by Thomas W. Murphey - exploiting the bi-stable nature of composite shells. Experimental tests were also carried on a boom prototype suspended in a gravity off-loading system. The strain energy level, deployment time and spacecraft displacements of the models agree well with analytical analyses, confirming the theoretical accuracy of the finite element model. However, the simulations show that the boom deploys six times faster than the real prototype. The quick deployment and violent end-of-deployment shock provokes the boom deployment dynamics to be unrealistic but still shows a reasonable behavior given the nature of the deployment. Future improvements in the material and friction models will, most likely, provide us with a more realistic finite element model.
