The principal, ultraharmonic and subharmonic resonance of an elastic rotation shat with twin sides by a harmonic force is discussed, in this paper.

Moreover, the multiscale method was used to study the main, ultraharmonic and subharmonic resonances of nonlinear rolling in waves, and the approximate solutions of the three resonances were given.
