FMECA of key components of circular truss antenna

Circular truss antenna is a new form of satellite antenna, where is the key deployment trend to the satellite. The truss elements, including some key components such as Sync hinge joint, T hinge joint, and bars, are the basic units to build the circular truss. Failure mode, effects and criticality analysis (FMECA) for the key components of the circular truss is given in the paper.
