..., and dynamic forces acting on the pump components as a function of angular rotations of both the main shaft and the yoke in the time and frequency domains. These elements address the harmonics of the forces acting on the case of the pump and will be presented in a future paper. The model was constructed using...

... shown that a torque is influenced by the dynamical behavior of the rotor. A nonideal shaft carrying two disks ( 5 ) Coordinate system of the nonideal rotors The external damping forces are considered to be proportional to the displacement velocity of the disks with χ 1...
