A practical TBM cutter wear prediction model for disc cutter life and rock wear ability

Tunnelling and Underground Space Technology, 2019
Abstract Tunnel Boring Machine (TBM) is an effective machine for building hard-rock tunnel. However, the interaction between the cutter of TBM and rock is the key factor before engineering construction, which will cause a lot of unnecessary losses and trouble in the construction process. The reason is that the disc cutter, the core tool of TBM broken

Improvement of Disc Cutter Performance by Water Jet Assistance

Rock Mechanics and Rock Engineering, 2013
This article deals with the problem of assisting disc cutters by means of high-velocity jets of water, with the aim of increasing the excavation rate while improving the working conditions, with particular reference to wear. The results of an experimental research undertaken at the Waterjet Laboratory of the University of Cagliari on a medium–hard ...

Analysis of thermal stress distribution of TBM disc cutter

Australian Journal of Mechanical Engineering, 2018
ABSTRACTThe disc cutter is used in the excavation of hard rock as one of the driving parts, so it is necessary to study the variation and distribution of thermal stress caused by contact friction with rock during the excavation. In this paper, the numerical simulation analysis of the rock breaking process of the disc cutter was carried out by using the

ANSYS-Based Finite Element Analysis on TBM Disc Cutter

Advanced Materials Research, 2014
The purpose of the essay is to know the rock fragmentation mechanism of TBM and improve the efficiency of disc cutter. The method of simulation is applied. The cutter ring and cutter axis surface stress distribution are studied under different rocks and the change of them is analyzed under different penetrations.

Effect of geometrical characteristics of TBM disc cutter on rock excavation: a focus on cutter diameter and cutter tip profile

Géotechnique Letters
Disc cutters are the most commonly used cutting tools in various types of tunnel boring machines (TBMs). Estimating the force required for cutting a specific type of rock using disc cutters is a crucial aspect of the TBM cutter head design and the prediction of TBM performance.
