Nonlinear dynamics of one disk elastic rotor is treated. The shaft is attached in two arbitrary length journal bearings. Unbalance between disk center mass and point of disk attaching to the shaft takes place. The forced vibrations occur due to this unbalance, which always present in a disk. The sel...
