| Abstract: | In this paper, a 2 D axisymmetric finite element model of a large size horizontal screw decanter centrifuge drum with double tapered beach was established by ANSYS. The static analysis of monolithic construction of the drum under a normal functional mode was performed. Besides the radial and axial deformation, the stress distribution and the maximum stress location of the drum were obtained. The results demonstrate that the double tapered beach configurations by the strength and stiffness assessments of the drum with double tapered beach are reliable. |
