Influence of the fibre spring-damper computational models in a mechanical system on the coincidence with the experimental measurement results

Popis výsledku v původním jazyce

Experimental measurements focused on the investigation of a fibre behaviour are performed on an assembled weigh-fibre-pulley-drive mechanical system. The carbon fibre, which is driven by one drive, 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. In presented case the position of the weight is symmetric with respect to the plane of a drive-pulley symmetry. Drive excitation signals can be of different shapes with the 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 multibody model. The influence of dependences of the fibre spring-damper coefficients on velocity of the weight motion in the computational model on the coincidence of the simulation results and the experimental measurement results is evaluated. The simulations? aim is to create a phenomenological model of
