Abstract

A 3-D solid finite element modal of a horizontal screw decanter centrifuge drum was established by ANSYS. The static analysis and modal analysis of the drum under a normal functional mode were performed. The results demonstrate that the strength and stiffness assessments of the drum are reliable, and the sympathetic vibration will not happen in normal rotate speed.
