STABILITY OF COUPLED STEADY STATE MODES AT PRIMARY RESONANCE IN NONLINEAR 2DOF SYSTEMS WITH CLOSE NATURAL FREQUENCIES

The interaction of external and 1:1 internal resonances in 2DOF nonlinear systems with symmetric cubic characteristics is studied. Steady–state modes in undamped systems are studied, with an emphasis on stability properties of coupled steady-state modes (CSMs) that appear in a vicinity of the primary resonance.
