This research shows the performance of the strength analysis and dynamic analysis of
the shaft strength of a centrifugal pump in an integrated NASTRAN / PATRAN system. There
is conducted the calculation of a mechanical scheme for determining the stress-strain state of the
rotor shaft of a centrifugal pump and constructed a 3D-model of the rotor of a seven-step
centrifugal pump. Furthermore, there are determined voltage levels for zero and maximum flow.
On the basis of these dynamic calculations, a damping element has been proposed that ensures a
smooth entrance of CP into an operating mode - a magnetic coupling.
