Abstract:

Cutterhead is one of the critical components of shield machine, which possesses such functions as cutting ground, stabilizing the working face and mixing the excavated materials. The cutterhead stands in the front line where the shield machine itself closely contacts with the geological conditions. By analysis on the case of the cutterhead development, this paper briefly presents the basic design methods and manufacturing process of cutterhead as well as the achievements of the industrialscale experiments of the cutterhead model.

Key words: cutterhead  , geology adaptability design method  , manufacturing process  , industrialscale experiment
