A Numerical Investigation of TBM Disc Cutter Life Prediction in Hard Rocks
There is a direct relationship between the efficiency of mechanized excavation in hard rocks and that of disc cutters. Disc cutter wear is an important effective factor involved in the functionality of tunnel boring machines. Replacement of disc cutters is a time-consuming and costly activity that can significantly reduce the TBM utilization and advance rate, and has a major effect on the total...
متن کاملEvaluation of Disc Cutter Performance in Rock Cutting Process Using 3D Finite Element Method
Today, numerical simulation can be used as a suitable tool to measure large quantities that are very expensive and, in some cases, impossible to measure. One of the important issues in predicting rock mass boreability in excavation with full face tunnel boring machines is estimating the discchr('39')s forces for rock cutting. For this purpose, the linear cutting test is employed. However, limi...

Based on heat conduction theory to establish disc cutter cutting temperature heat conduction model, and derive its solution; analyze influence on disc cutter cutting tempe...
متن کاملFlow Field Analysis of Cutter Head for Cutter Suction Dredgers
For a cut ter suction dredger, exploring slurry formation mechanism plays an important role for improving the dredger’s efficiency and performance. In order to optimize the dredger’s working parameters, the flow field is simulated for the cutter head of a cutter suction dredger in this study. First, Cutter’s 3D model is const ructed by 3D Modeling software after necessary parameters are collect...
