摘　　要：针对全断面硬岩隧道掘进机(TBM)油缸并联推进系统产生的推进干扰力降低关键部件使用寿命和隧道开挖精度的问题,提出姿态自适应推进系统.建立推进机构的数学模型,将推进油缸分为2组,对2组推进油缸的大腔压力进行动态分配.使用ADAMS AMESim Simulink三软件联合仿真,对比分析并联推进系统与姿态自适应推进系统.结果表明:在额定推进力和0.1°、0.3°、0.5°调向角度下,姿态自适应推进系统产生的推进干扰力为并联推进系统的2%,姿态自适应推进系统平行于主梁的推进正压力的超调小于5%.姿态自适应推进系统可以显著减小推进干扰力,具有良好的稳定性.A new adaptive attitude（ADA）tunnel boring machine（TBM）thrust system was proposed to overcome the problem of the service life of critical components and tunnel excavation precision reduced by disturbing force produced by four cylinders connected in parallel（CCP）thrust system.The mathematical model of thrust mechanism was established.Four cylinders were divided into two groups and working pressure of each group was adjusted in real time.The comparison of ADA thrust system and CCP thrust system was conducted by using co-simulation of ADAMS AMESim and Simulink when the deflection angle was 0.1°,0.3°and 0.5°under rated thrust force.Results showed that the disturbing force in ADA thrust system was 2% comparing to disturbing force in CCP thrust system.The overshoot of force paralleled to main beam in ADA thrust system was less than 5%.ADA thrust system can significantly improve performance in reducing the disturbing force,and the system has a good stability.
