Analysis of Synchronous Regimes of the Biharmonic Oscillator

This paper considers a biharmonic oscillator, which operates in the phase locking states of two wave modes with a multiplicity of frequencies 2. The article shows that the phase locking state is preserved in the presence of inertia of the active element. The truncated differential equations for the slowly varying amplitudes and phases of oscillatory modes are obtained. The effect of the magnitude of inertia of the active element of a biharmonic oscillator on the amplitudes and phase difference of the generated oscillations has been studied. Solutions are obtained by analytical analysis a system of truncated differential equations at low inertia of the active element in the stationary mode.
