Abstract. The subject of study in this paper is forced nonlinear vibrations of antivibration mountings of the machine, taking into account the frequency-dependent viscous friction.
Purpose. The aim is to use an approximate analytical method of harmonic balance to investigate the influence of the cubic nonlinear characteristics on the amplitude of the restoring force on the forced vibrations of the machine antivibration mountings.
