Mobility Analysis of a Large Deployable Reflector Antenna

Résumé

Large deployable reflector antennas are complex closed chain systems which are capable of significantly altering their size by modifying configuration space variables. The kinematic analysis of such mechanisms is essential to understanding their behavior during deployment and aid the synthesis of new design as well as establishing the mobility of the system and the most efficient actua-tion configurations. In this paper, we analyze one facet of a large scale deployable antenna, which during deployment undergoes a homothetic transformation. The geometric properties are analyzed under assembly conditions. Furthermore, we show by using screw theory that such a mechanism is feasible and the nature of the motion is demonstrated.
