摘　　要：盾构机用于市政修建时,其设计轴线与施工隧道的偏差是衡量施工质量的重要指标,故液压缸的精确控制十分重要。首先分析德国海瑞克R438盾构机推进系统控制原理,其次利用AMESim搭建压力和流量开、闭环仿真模型。由仿真结果可知:开环控制下,压力(流量)改变时,流量(压力)随着会发生大的波动;闭环控制下,压力和流量之间的相互影响作用被大大削弱。因此,得出压力流量双闭环控制可以更好地满足推进系统的控制要求。In this paper, firstly, the control principle of the propulsion system of Herrenknez R438 shield machine is analyzed. Secondly, the simulation models of open-loop control and closed-loop control of pressure and flow are built by using AMESim. The results show that the flow rate （pressure） is of big fluctuations by open-loop control. In the case of closed-loop control, the interaction between pressure and flow is greatly weakened. Therefore, the pressure flow dual closed-loop control can better meet the control requirements of the propulsion system.
