Research on TBM Disc Cutter Wear Prediction Based on CSM Model
摘要
The wear of disc cutters significantly impacts the efficiency and cost of TBM operations. In this study, we established a calculation model for radial wear based on the CSM formula and abrasive wear mechanisms. Experimental validation of the wear mechanism confirmed that abrasive wear is the primary mechanism responsible for disc cutter wear. The predictive model was subjected to engineering validation, where the calculated values from the model were compared and analyzed against actual on-site measurements. This validation process confirmed the accuracy and applicability of the model.
