| Abstract: | Oscillations of a haulage rope of mobile pendant timber transport installation are explored. In the differential equation of transverse oscillations of a longitudinally moving rope nonlinearity of its mechanical properties is taken into account. This nonlinearity is described by Calvin-Voigt viscoelastic model. The solution of feeblly nonlinear differential partial equation is constructed with use of a method of Krylov-Bogolyubov-Mytropolskiy method and sent as an asimptotical series. The differential associations obtained on the basis of the constructed solution for amplitude and phases of transverse oscillations allow to investigate agency of length of a section of a rope, a velocity of its longitudinal motion and a dynamic viscosity on amplitude and an oscillation frequency |
