Implication

This research demonstrates improved wear resistance of a novel cutter ring material in TBM, indicating enhanced tunneling efficiency.

Key Points

The aim is to develop a cutter ring material that improves wear resistance and efficiency in tunnel boring machines under challenging geological conditions.
Developed a cutter-rock contact model using ABAQUS for simulations.
Simulated stress distribution, crack propagation, and mechanical characteristics during rock-breaking.
Utilized plasma cladding technology to create a novel cutter ring material.
Conducted experimental evaluations to compare the service life and efficiency of the new cutter material.
The new cutter ring material extends service life by over 20%.
Improved TBM efficiency observed, reducing cutter replacement frequency.
Significant decreases in maintenance costs were recorded.
