摘要 为了提高盾构刀盘驱动液压系统的效率,以6.3m土压平衡(EPB)盾构和1.8m模拟盾构为研究对象,提出两种新型盾构刀盘驱动液压系统.对比分析了常用的多泵联合驱动和新提出的多泵组合驱动方式的刀盘驱动液压系统效率,常用的变排量容积调速和新提出的变转速容积调速驱动方式的刀盘驱动液压系统效率.建立了液压泵和液压马达的效率计算模型,采用AMESim软件建立4种液压驱动系统的仿真模型.研究结果表明,在刀盘典型转速下(1.0~2.0r/min),多泵组合驱动方式比多泵联合驱动方式的刀盘驱动液压系统效率高3%~7%,变转速容积调速方式比变排量容积调速方式的刀盘驱动液压系统效率高4%~26%. Two novel hydraulic drive systems were proposed by analyzing the 6.3 m earth pressure balance (EPB) shield machine and the 1.8 m test shield machine in order to improve the efficiency.The efficiency under the multi-variable pumps joint mode was contrasted with the multi-variable pumps built-up mode,and the variable displacement pump control mode was contrasted with the variable rotate speed pump control mode.The efficiency calculation models of the hydraulic pump and hydraulic motor were conducted,and the simulation models of the four hydraulic systems were conducted by AMESim soft.The efficiency of the multi-variable pumps built-up mode is higher than the multi-variable pumps joint mode about 3%-7% and the efficiency of the variable rotate speed pump control mode is higher than the variable displacement pump control mode about 4%-26% at the typical rotate speed of 1.0-2.0 r/min.
