摘要

The ITER (international thermonuclear experimental reactor) tractor is an in-cask remote handling equipment,its tilting and lifting mechanism is important for the tractor operated with forty-five-ton plug in front of the ports of Hot Cell and VV (vacuum vessel) successfully.In order to better analyse the movement of this mechanism and decide the key design parameters accurately,a mathematical model of 7-1ink complicated plane mechanism was built up,and the calculation of design and kinematics simulation were implemented.The established mathematical model was proved to be valid by comparing the calculated result with that of kinematics simulation.Finally,the structure analysis and the optimization of its key part,tilting and lifting frame,were performed to guarantee the frame's strength in bearing the heavy load of plug.
