Abstract A Gripper and Thrust hydraulic system with the function of Load-Sensing, Constant Pressure control and auxiliary support of accumulator (LSCPGT) was proposed to overcome the problem of high relief loss in the hard rock Tunnel Boring Machine (TBM) gripper and thrust system after gripper reached a preset pressure. Model of LSCPGT system was established by AMESim. The pressure and flow responses of LSCPGT system were analyzed, and the pressure and flow responses of Constant Pressure Gripper (CPG) system were compared with that in gripper system, and the pressure and flow responses of Load-Sensing Thrust (LST) system and Ration Thrust (RT) system were compared with that in thrust system. The results indicated that LST system and LSCPGT system had no flow loss during the thrust process. In gripper system, the CPG system had certain flow loss under the support condition, but the LSCPGT system had no flow loss with the help of accumulator. Moreover, compared with the gripper and thrust system composed of LST system and CPG system, LSCPGT system improved at least 43.5% in efficiency after gripper reached preset pressure. The designed LSCPGT system which meets the demand of gripper and thrust can save energy through avoiding flow loss.

TBM试验台支撑推进节能系统设计与仿真分析
针对全断面硬岩隧道掘进机（hard rock tunnel boring machine，简称TBM）在撑靴以设定压力撑紧围岩后支撑推进系统存在较大流量损失的问题，设计出一种具有负载敏感、恒压控制和蓄能器辅助支撑功能的支撑推进（简称LSCPGT）系统。利用AMESim软件搭建了LSCPGT系统模型，仿真分析了LSDRGT系统在变推进负载下的压力流量响应，并对比分析了在支撑工况下LSCPGT系统和恒压控制泵型支撑（constant pressure gripper，CPG）系统，以及在推进工况下LSCPGT系统与负载敏感泵型推进（load-sensing thrust，LST）系统和定量泵型推进（ration thrust，RT）系统的压力流量响应.结果表明：LST系统和LSCPGT系统在推进过程中都没有流量损失；CPG系统在支撑工况下存在流量损失，而LSCPGT系统由于蓄能器的保压作用没有流量损失；相对于LST系统+CPG系统的支撑推进系统，LSCPGT系统在撑靴达到设定压力后效率至少可提高43.5%。所设计的LSCPGT系统在满足支撑推进要求的同时，避免了流量损失，具有较好的节能效果。
