摘要/Abstract

摘要： 在隧道掘进机刀盘的实际使用过程中，盘体的疲劳失效较为严重。针对隧道掘进机刀盘的极端使用环境和复杂结构导致刀盘过早失效的问题，结合以往的隧道掘进机刀盘失效数据，建立了一种计算空间裂纹扩展的方法。在隧道掘进机刀盘本身结构的基础上，研究了加筋板的形状和参数对裂纹扩展阻力的影响规律，进而提出了隧道掘进机刀盘的抗损伤和抗裂纹方法。研究结果为隧道掘进机刀盘结构设计提供了依据和方法。

Abstract: 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.
