The bending torsional vibration model of a rotor with one disc is shown first, and the dynamical characteristics about bending torsional vibration of a rubbing rotor are analyzed. Several basic concepts are shown, and the exciting force form and the changes of rigidity and damping in bending torsional vibration of a rubbing rotor are analyzed. The nonlinear differential equation of bending torsional vibration of a rubbing rotor is then established. Then, the numerical analysis of rubbing rotor is accomplished. Some conclusions are deduced at the end of the paper and the characteristics of the influenence of torsion to bending are found.
