摘　　要：刀盘作为全断面岩石掘进机(TBM)的关键部件,其应力分布、变形量能否满足要求对掘进性能有很大的影响。以TBM刀盘为研究对象,通过建立刀盘有限元模型,依据罗宾斯公司提出的3种新工况,通过Workbench软件分析了在不同复杂工况下刀盘整体及其各分体的变形和应力分布,发现法兰与支撑筋的焊接部位应力最大且各肋板连接部位易出现应力集中,因此建议增加支撑筋与法兰的焊接面积并优化过渡方式,为后续的结构优化提供参考。The cutterhead is the core component of the full face rock tunnel boring machine（TBM）,and whether the deformation is satisfied or not and whether the stress distribution is reasonable or not have a great influence on the driving performance.TBM cutterhead designed for Xinjiang river water diversion project was taken as the research object.Through the establishment of finite element model of the cutterhead,according to three new cases proposed by Robbins′s,the deformation and stress distribution of the whole cutterhead and its division under different complex conditions were analyzed by Workbench software.The results show that the maximum stress appears in the welding part of flange and the support brace,and stress concentration phenomena are prone to appear in the rib joints.Therefore we propose to increase the welding area and optimize the transient mode.This study may provide reference for subsequent structure optimization.
