Overview

Analysis reveals improved torque predictions in full-face rock tunnel boring machines, indicating enhanced accuracy for engineering applications.

Key Points

  • This research aims to develop a theoretical framework for predicting cutterhead torque in full-face rock tunnel boring machines.
  • Examined rock-breaking characteristics of the disc cutter on the cutterhead.
  • Analyzed lateral friction resistance compared to inner and outer rock breaking.
  • Proposed a torque composition model including shoveling, rolling resistance, and lateral imbalance torques.
  • Validated theory through practical engineering verification.
  • Achieved a relative error of 0.51% between theoretical and actual cutterhead torque values.
  • Noted a 7.48% error when ignoring lateral friction and imbalance moments.
  • Established torque theory showed 6.97% higher accuracy than previous linear rolling crushing test theory.
