By virtue of bifurcation diagrams, Poincaré maps, orbits, time histories and frequency spectrum diagrams, the nonlinear dynamic responses of the generator rotor and hydraulic turbine rotor with coupling faults were analyzed. The results confirmed rich nonlinear motions such as periodic motion and quasi-periods with different values of parallel misalignment and declination. Moreover, the process of rub-impact is so complex that many low frequencies with large amplitude are in the range of
