Abstract

In view of the special situation that the shield machine cannot be removed from the tunnel when meets the cutter head, and it must be decomposed and disassembled before it can be taken out in blocks, needing to construct the three-dimensional model of the cutter head, and the structural statics finite element simulation of the three dimensional model of the cutter head under normal working condition and 1/3 radius plugging condition is carried out by using the relevant software, and the stress-strain law of the cutter head under these two conditions is analyzed. Based on the analysis of the structure of the cutter head, the core position of the cutter head, the degree of difficulty in recovery and the size of the block, a reasonable dis-assembly scheme for the cutter head of the large diameter shield machine is designed.
