A technique for determination of vibration modes of nonlinear coupled parametrically self excited oscillators is presented in the paper. The method is applied for vibration regions ii which the synchronisation phenomenon takes place and the system vibrates with singli frequency. The, so called, resonant Nonlinear Normal Modes (NNM) are determined inside these resonance regions. The NNMs are defined on the basis of natural vibrations o a nonlinear system, as nonlinear functions of amplitude. Correctness of the results ii verified by direct numerical simulations.
