Dynamic characteristics of stationary impellers can be analyzed accurately by the Cyclic Symmetry Method; however, it is necessary to calculate dynamic characteristics of rotating impellers. In this report, equations of motion and those of vibration for rotating impellers which are divided into finite elements by the F.E.M. are presented. In these equations, effects of centrifugal forces and Coriolis' forces on dynamic characteristic.s of rotating impellers are considered. In this report, it is made clear that critical speeds and critical modes can be found in connection with centrifugal forces and that computation of natural pairs considering Coriolis' influence resolves into eigenvalue problems of Hermitian matrices.
