In the actual service process of the tunnel boring machine(TBM)cutter head,the fatigue failure of the disc body is serious.Aimed at the problem of premature failure of cutter head due to the extreme service environment and complicated structure of the TBM cutter head,the previous TBM cutter head failure data are combined to establish a method for calculating the space crack growth in this paper.Based on the structure of the TBM cutter head itself,the law of the shape and parameters of the stiffened panels on the crack propagation resistance is studied to further present the method of anti-damage and anti-crack for the TBM cutter head.The results illustrate that the basis and methods for the structural design of the TBM cutter head are put forward.
