| Abstract: | In this paper, we discuss the hopf bifurcation in a two degree of freedom almost linear system with closely spaced natural frequencies under 2 ultraharmonic resonance. We also point out that the system will have very complicated phenomena by the internal resonance due to closely spaced natural frequencies. |
