Abstract:
This study concerns vibration phenomena induced by the passage of a vehicle in hold-down towers of monocable ropeways and by the chocks produced by the clip on the-sheaves-battery rollers.A dynamic model is developed for the “tower-sheaves battery-vehicle”system. This model takes into account the influence of the vehicle weight and inertia as well as the dynamic characteristics of a 16-rollers symmetric sheaves banery and those of the tower.In order to validate the model experimental data were obtained in industrial equipament. Their spectral structure were determined by two analysis mediods: the first one is based on Fourier transform while the other is a parametric hybrid method, the so called AR-CAP (Autoregressive-Capon) method that makes it possible the analysis in the time-frequency plane.
