Drgania gietne wału z tarczami kołowymi w ruchu ustalonym

The paper presents the process of creation and solution of coupled differential equations describing bending vibrations of the shaft with thin circular discs mounted centrically on it, rotating with a constant angular velocity. The influence of shear strains on the equations is neglected, because of their relatinely small value on a circular section of the shaft. The influence of gyroscopic moment corresponding to the discs and the shaft is taken into consideration: the discs are assumed to be rigid and discrete. At the end of the paper the relations for bending vibrations forced by transverse concentrated and uniformly distributed forces are defined.
