| Abstract: | Based on the finite element analysis (FEA), the critical speed of vertical shaft system was calculated by a self-developed computing model of a dish centrifuge. The stiffness of upper bearing was considered sufficiently in calculation. In order to verify the calculated result, the vibration modes of a dish centrifuge were tested and measured. The comparison of the results from the calculation and the measurement proved a good coincide between them. The influences of structural parameters, such as mass and height of the bowl, supporting stiffness of upper bearing, participating mass, etc., on critical speed were analyzed. |
