Design and analysis of the hydraulic driving system for the circular transfer platform of the CFETR divertor

In this study, a single-pump closed-loop hydraulic system with multiple actuators and load sensitivity is designed for a circular transfer platform, which remotely handles the divertor of the China Fusion Engineering Test Reactor by rotating the divertor module in the non-maintenance window to the designated position along the circular track. The proposed system controls the position and force of the pushing and locking cylinders. The designed closed-loop system synchronizes the movements of the internal and external cylinders. It also controls the displacement and force of the locking cylinder, ensuring the stability of the clamping force and the controllable position of the cylinder. Furthermore, the dynamic performance of the hydraulic control system is verified via the Adams-AMESim software co-simulation.
