Kinematics Analysis of Double Seal Door for ITER Remote Handling Transfer Cask System

The moving direction of double seal door (DSD) of ITER remote handling transfer cask and the force of hydraulic pole will change significantly at the guide rail inflexion position (GRIP) which is a mutant site, so it is very possible to make the structure damage or the system failure at the GRIP. In this paper, the kinematics simulation and analysis of DSD were done based on special constitution restriction and working process by software ADAMS. The stress distribution of guide rail and hydraulic pole were obtained by the above simulation, at the same time the optimal GRIP was confirmed according to the force analysis result. The above-mentioned analysis process and results not only provide technical data for the optimization design and the prototype manufacture of DSD, but also provide the examples and references of kinematics analysis for other important components of ITER.
