The characteristics of the hydraulic piping system in Tunnel Boring Machine (TBM) are large slenderness ratio, high fluid pressure and low flow velocity. With the work conditions of TBM, the beam model of long straight pipe was established. Under consideration of fluid structure interaction (FSI) and simple supported conditions, oscillation equation of piping system was solved by vibration formation decomposition. Having analyzed the effect of piping system parameters on the first order inherent frequency by the method of sensitivity analysis, pipe length was the most significant effective factor on inherent frequency of pipe system. Considering the relation between fluid pressure wave frequency and pipe inherent frequency, oscillation criteria based on the first order inherent frequency was put forward. Finally, optimized design was given for piping system design. © 2010 Springer-Verlag.
