摘要：
A vertical hard gyroscopic rotor at that a disk has a defect and disbalance of mass is examined. For complete description of motion of rotor the dynamic model of machine is built. Expressions of kinetic energy, nonlinear function of Relay are found for this purpose, to potential energy of rotor taking into account geometrically nonlinear description of resilient support, moments of external forces and worked out equations of motion in form Lagrange. Expressions of amplitude and phase of main accordion are certain the method of decomposition in the row of Fourier of decisions of equalizations of the forced vibrations and method of harmonic balance and influences of mental instability are investigational on resonant vibrations and stability of rotor.
