  • Abstract:
  • Deployable structures have been integral and crucial elements of spacecraft missions ranging from large deployable booms to reflector antennas and even a robotic arm. This paper brings out one prospective design solution for the deployment mechanism for a deployable planar antenna within given design considerations and constraints. The paper also presents various factors influencing the design of deployment mechanisms, including precise latching and launch environmental conditions. This work aims to simulate the deployment mechanism in a 3-D CAD environment and simulate the unfolding process of the planar antenna. Modeling the unfolding process with sequencing and latching mechanisms is one of the challenges addressed here. The software tool used for 3-D CAD simulation is Autodesk Inventor, whereas, Ansys rigid body dynamics is used to perform the dynamics and kinematics simulation of the arrangement. Design sensitivity has been checked by varying design parameters such as COF and spring stiffness. Static analysis of loaded components is performed in the Ansys transient structure environment. The results are compared with the requirements and limitations for the space missions.
