摘要

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 cartier is built with Pro/E.After the load on the cartier 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 cartier and planetary gear shaft because of the bending deformation of the shaft.
