Abstract
Experimental measurements focused on the investigation of a fibre behaviour are performed on an assembled
weigh-fibre-pulley-drive mechanical system. The fibre is driven with one drive and it is led over a pulley. On
its other end there is a prism-shaped steel weight, which moves in a prismatic linkage on an inclined plane. The
position of the weight is asymmetric with respect to the vertical plane of drive-pulley symmetry. Drive exciting
signals can be of a rectangular, a trapezoidal and a quasi-sinusoidal shape and there is a possibility of variation
of a signal rate. Dynamic responses of the weight and the fibre are measured. The same system is numerically
investigated by means of a multibody model. The influence of the mass of the weight and the influence of the
weight asymmetry on the coincidence of results of experimental measurements and the simulations results are
evaluated. The simulations aim is to create a phenomenological model of a fibre, which will be utilizable in fibre
modelling in the case of more complicated mechanical or mechatronic systems.
