摘　　要：以海瑞克盾构液压推进系统为研究对象,建立了管道压力波动数学模型,分析了管道特性对液压推进单缸位移传递的影响.基于AMESim软件对系统进行了建模和仿真,讨论了盾构推进液压系统的管道特性及管道结构参数对推进缸位移动态性能的影响.结果表明:管道长度与管道直径是影响推进缸位移与值构纠偏距离的关键因素,管道长度越长、管道直径越小,管道特性在推进缸位移上的体现越明显.This paper studies the hydraulic thrust system of Herrenknecht shield machine, establishes the mathematical model of pressure fluctuations of pipeline and analyses the pipeline effect on the shield thrust cyl-inder displacement. Modelling and simulation of the hydraulic system based on the AMESim software. It also discusses the influence of pipeline effect on the shield hydraulic thrust system are made and pipeline structure parameters on the dynamic performance of shield thrust cylinder displacement. The results show that the pipe length and diameter ane key factors influenciny the trust cylinder displacement and shield correction distance, what＇ s more,the longer the pipeline length and the smaller the pipe diameter,the pipeline effect is more obvi-ous on the trust cylinder displacement.
