Abstract

The effective simplification of the iteration method of construction of the nonlinear normal vibration modes by Shaw-Pierre taking into account the inner resonance is proposed. The simplification consists of the system partial reduction to principal coordinates, which affects only active coordinates having the largest amplitudes. It is shown that the modified method can be successfully used in a problem of the one-disk rotor on nonlinear flexible inertial supports dynamics.
