- Abstract:
-
According to the structural characteristics of a cutterhead of an EPB shield, a three-dimensional solid model was established in Solidworks, and the corresponding finite element calculation model of the cutterhead was established by ANSYS software, and the stress and strain distribution law of the cutterhead under normal working conditions and escape conditions was analyzed, and the stress-strain distribution law of the cutterhead under each working condition was obtained. The analysis results show that the dangerous section is located between the auxiliary beam and the auxiliary bar at 180~210°, and there is also a large stress at the connection between the corbel, the flange plate and the auxiliary beam, the maximum stress is 204 MPa, and the maximum deformation is 1.568 mm, and the research results provide basic data for the structural design and engineering construction maintenance of the cutterhead.
