Abstract
Hydraulic thrust system is an important system on a shield tunneling machine. Pressure regulation of thrust cylinders is the most important function of thrust system during tunnel excavation. In this article, a hydraulic thrust system is illuminated, and a corresponding simulation model is carried out in order to study the system characteristics. Pressure regulation of a certain group’s cylinders has a little influence of the other groups’ cylinders. The influence will not affect the process much during tunnel excavation. Pump displacement may have a great effect on the pressure regulation. Oil supply flow rate should be adaptive to the system demand. A tough situation is simulated to explain how the pressure regulation works during tunnel excavation.
