Abstract
On the basis of the developed analytical model of the motion of a deformable Earth relative to the center of mass, the disturbed motion of the Earth’s pole is investigated. Taking into account the influence of the pole tide by linear and nonlinear dissipative terms, as well as disturbances at close to the Chandler frequency, corrections to the frequency and amplitudes of the Chandler oscillations depending on the dissipation coefficients were found in the equations of motion of the Earth’s pole.
