摘要

边缘滚刀安装在全断面隧道掘进机(TBM)刀盘的最外缘，在破岩时边缘滚刀的受力情况十分复杂，工作条件恶劣，容易损坏。为研究布置参数对边缘滚刀的影响，采用有限元分析软件ABAQUS建立边缘滚刀破岩的非线性动力学模型，分析边缘滚刀的受力情况。结果表明：边缘滚刀在破岩时所受的作用力会剧烈振荡变化；安装倾角和刀盘过渡圆弧半径对边缘滚刀受力的影响显著；边缘滚刀受力随着安装倾角和刀盘过渡圆弧半径的增加而呈现近似线性的增长。

Abstract

Gage disc cutters installed on the edge of cutterhead of fullface tunnel boring machine (TBM) are subjected to complexity of stress due to the bad working conditions. Nonlinear dynamic models are established by using ABAQUS software so as to study the influence of layout parameters on stress of gage disc cutter; and the stress on the TBM gage disc cutter is analyzed. The results show that: 1) The stress on the gage disc cutter during rock breaking varies violently. 2) The installation angle and transition arc radius have a significantly influence on the stress of gage disc cutter. 3) The stress on the gage disc cutter increases approximately linearly with the installation angle and transition arc radius increase.

Key words： TBM; gage disc cutter; installation angle; transition arc radius; finite elements
