为研究掘进机盘形刀盘在干燥、水和海水条件下的磨损行为，在自行设计的掘进机刀盘性能试验台上进行了刀盘-岩石磨损试验。结果表明，刀具环的磨损行为受磨损条件的影响很大。干燥条件下刀圈的质量损失最大，海水条件次之，有水条件下最小。从切削力、磨损机理、磨屑等方面解释了两种方法的质量损失差异。研究结果可为TBM刀圈的耐磨设计和寿命预测提供参考。
To study the wear behaviors of the tunnel boring machine (TBM) disc cutter ring under drying, water and seawater conditions, a series of cutter-rock wear tests were conducted based on the self-designed TBM cutter performance test bench. The results indicate that the wear behaviors of the cutter ring are affected significantly by wear conditions. The largest mass loss of the cutter ring is under the drying condition, followed by the seawater condition, and the smallest is under the water condition. The differences in mass loss were explained by the cutter force, wear mechanism, and wear debris etc of the cutter ring. These results can provide some references for the wear resistance design and service life prediction of the TBM cutter ring.
