摘　　要：随着我国隧道掘进长度的增加,隧道掘进效率和自动化掘进并重的观点在安全掘进中日益凸显,环缝钻车在振动、噪音、精确控制和静态掘进钻孔等方面有显著的优势。但目前环缝钻车点的液压系统在隧道全断面自动化、智能化、高效化以及更高的钻孔要求等方面与实际需求相差较大。本文依据环缝切割的机理和定位功能的要求,对环缝钻车的推进钻削液压系统等进行了研究,并利用AMESim仿真软件对液压系统进行了仿真,研究结果验证了液压系统具有较强的速度刚度,且工作装置液压系统的抗流量饱和能力与设计的预期值基本一致,液压系统设计能满足要求。The girth drilling rig has significant advantages in the aspects of vibration, noise, accurate control and static boring.However, at present, the hydraulic system of the girth drilling rig cannot meet the demands for automatic, intelligent, and efficient tunnel boring.According to the mechanism of the girth drilling rig and the requirements for the positioning function, we studied the propulsion drilling hydraulic system of the girth drilling rig, and simulated the hydraulic system with AMESim simulation software.The research results show that the hydraulic system had strong speed stiffness.The anti-flow saturation capacity of the hydraulic system is basically consistent with the expected value of the design, and the design of the hydraulic system meets the requirements.
