Cutter head is the key component of shield machine, in order to ensure the smooth running of dual-mode shield machine used for colliery inclined shaft engineer, it is necessary to study the strength and stiffness of cutter head. The loading calculation methods and equations were obtained by analyzing the mechanical characteristics of dual-mode shield cutter head in multiple conditions on basis of the study on the geological features of Xinjie colliery inclined shaft. According to the structure feature of dual-mode shield cutter head, simplified models were established.Then the regularities of distribution of stress and strain under different conditions were obtained by using ANSYS. Consequently, the results showed that:the maximum deformation was 3.821 mm appeared in EBP plug and turn condition, the maximum stress was 284 MPa appeared in TBM plug and turn condition. Furthermore,the maximum stress under multiple conditions was located in the connection of bracket and flange plate or the connection of bracket and cutter head. According to the results, the design of cutter head is reasonable, furthermore some improvement measures are came up with in terms of the weak parts.
