| Forced oscillations of a non-linear system with two degrees of freedom in the neighborhood of the principal resonance are investigated using the asymptotic method. The difference between two natural frequencies is assumed to be small. The nonlinear forces are the reason of a relation between the oscillations in different directions. |
