Abstract
In order to analyze the fracture of bolts at the flange of TBM cutterhead, the load distribution of the thread in the standard thread connection structure was studied. Based on theoretical analysis and Finite element simulation analysis, starting from the connection structure of bolt, the load distribution of a thread connection structure under axial load was studied, and the maximum stress at the root of each whorl was obtained by Abaqus simulation. Finally, the fatigue test of double threaded studs with standard thread connection structure was carried out. The load distribution law of each circle screw thread was verified through a set of stud fatigue fracture position. Found that the bolt fracture problem was not due to the excessive load on the flange, but due to the nouniform distribution of the axial force of the thread.
