Design and analysis of a Double Seal Door for the Tokamak Equipment CAsk(TECA)

The tele-operated transfer cask is required for maintenance in nuclear fusion environment. The Double Seal Door (DSD) is one of the key modules for automatic docking and sealing missions. The whole DSD system is designed and the prototype is accomplished. The tilting mechanism kinematics is equated and simulated, and the structure optimization is achieved. The tilting motion control experiments validate the analytic kinematics and the simulation. The average control deviation is about 9.7mm.
