Influence of the Mass of the Weight on the Dynamic Response of the Laboratory Fibre-Driven Mechanical System
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. An extra mass can be added to the weight. 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. Time histories of the weight position and of the force acting in the fibre are measured. The same system is numerically investigated by means of a multibody model. The influence of the mass of the weight on the coincidence of results of experimental measurements and simulations is evaluated. The simulations aim is to create a phenomenological model of a fibre, which will be utilizable in fibre modeling in the case of more complicated mechanical or mechatronic systems.
