盘形滚刀工况条件差、换刀成本高，生产厂家对刀圈的性能要求越来越严格。为了提高刀圈质量，针对TBM中43.2 cm（17英寸）盘形滚刀刀圈，采用轧制成形工艺，运用塑性成形软件，建立盘形滚刀轧制过程数值模型，通过有限元仿真分析滚刀成形的应力场和应变场，并对不同参数对成形过程的影响进行研究。研究结果表明： 1）轧制过程应力较小，应变分布较为均匀，但整体应变较小，随着主辊转速及芯辊进给速度的增大，等效应力逐渐减小，应变基本不变。2）匹配仿真参数进行刀圈轧制试验，并对刀圈质量进行检测，刀圈流线与外形轮廓相符，分布连贯不被打断，且与主应力方向一致，流线合理。

Due to the poor working conditions and high cost of replacement of disccutters, the manufacturers are getting stricter about the performance of the disccutter rings. The numerical model of rolling process of TBMused 17 inch disccutter is established by plastic forming software; the stress field and strain field of the disc cutter during rolling is analyzed by finite element simulation; and the influence of different parameters on disc cutter forming process is studied. The study results show that: 1) During the disccutter rolling process, the stress and strain are small, the strain distribution is uniform; with the main roller speed and the feed speed of the core roller increase, the equivalent effective stress decreases; while the strain does not vary. 2) The test on disc cutter ring rolling by matching the simulation parameters is carried out; the quality checking shows that the cutter ring circle, with continuous distribution and holds the same direction with main stress, coincides with the cutter contour.
