摘　　要：全断面竖井掘进机锥形刀盘在竖井施工中具有导向性好、姿态调整方便等优点,滚刀作为竖井掘进机施工中最直接的破岩工具,获取其载荷分布规律对于竖井掘进机的刀盘刀具系统的合理设计和掘进过程中装备姿态的调整具有重要意义。基于ADAMS建立了全断面竖井掘进机锥形刀盘与岩体耦合模型,合理施加约束条件对正常掘进工况进行仿真,获取了竖井掘进机锥形刀盘刀具的载荷分布规律。结果表明:由于安装方式的不同,正滚刀所受到的侧向力和滚动力均大于中心滚刀,对正滚刀刀座与辐条之间的连接强度提出了更高要求;随着正滚刀在刀盘上安装半径的增大,其受到的垂直力也增大。中心滚刀所受到合力载荷稳定性较正滚刀明显较好,波动更小;随着滚刀在刀盘上安装半径的增加,滚刀所受到的合力载荷大小波动更大,载荷稳定性也更差。The conical cutterhead of the full-section shaft boring machine possesses the advantages of good guidance and convenient attitude adjustment in the construction of the shaft.As for the dis cutters are the most direct rock-breaking tool in the shaft boring machine construction,it's full of meaning for rational design of the cutterhead tooling system and adjustment of equipment posture during excavation process to obtain the load distribution rules.The coupling model between the conical cutterhead and rock mass of the full section shaft boring machine was established based on ADAMS and the normal excavation of the machine was modeled by reasonably exerting the constraint condition.The load distribution laws of the conical cutterhead and cutters for the full section shaft boring machine were acquired.The results show that on account of different installation methods,the lateral force and rolling force of the positive rolling cutter are bigger than those of the central rolling cutter,which put forward higher requirements for the connection strength between the positive rolling cutter holder and the spoke.As the installation radius of the cutters on the cutterhead increases,the vertical force on it also increases.Compared with the positive rolling cutter,the resultant load of the central rolling cutters possesses better load stability with less fluctuation.As the installation radius of the cutter on the cutterhead increases,the stability of the resultant load on the cutter become worse with greater fluctuations.
