The method to analysis the strength of planetary trains’ carriers of EPB(earth pressure balance) shield machine is presented in this paper. The structure of the shield machine trains is analyzed and the 3-D solid model of the carrier is built with Pro/E. After the load on the carrier has been dealt with, the strength of carrier is calculated by means of finite element method. The results via ANSYS show that the max stress and strain on the carriers are increasing as the increasing load on it. The max stress is lying on the joint point of the carrier and planetary gear shaft because of the bending deformation of the shaft.

This paper introduced the characteristics of eccentric multi-axes rectangular shield machine and made comparisons to traditional earth pressure balance shield machine. And introduced structure form of eccentric multi-axes, and carried out calculation of cutter head driving. The author completed the finite element calculation of eccentric axis with COSMOS Works, the results of calculation shows that maximum stress occurs at the place at gear keyway of eccentric shaft, but the eccentric shaft can satisfy the requirements in shield design according to big load in cutting soil. Finally, the eccentric shaft was applied in several engineering cases without any structural problems.

Analysis and design cannot be solved until a proper model of hydraulic control system of earth pressure balance shield machine is built. There are two kinds of modeling methods in common use. (1) Dynamic mathematical modeling. Two models, transfer function and state space, are mainly included. For linear system, the two methods can be provided with a fairly complete theoretical framework. However, if the system is in the complicated working environment or it is non-linear, the modeling process needs a mass of mathematical verification. This has become a limitation for application of these methods; (2) Graphical Modeling. It is more direct for the complex hydraulic control system of earth pressure balance shield machine. First, the main components are separately modeled. Then connect them according to the flow direction of signal. Some special software, such as AMESim, can be used to simplify the simulation process.
