Analysis of vibrations of a cable-pulley system using the absolute nodal coordinate formulation

Popis výsledku v původním jazyce

Cable vibrations can have an important e ect on the motion of a whole mechanical system and therefore it is reasonable to investigate the dynamic behaviour of such systems including these structural parts. This paper deals with the application of the absolute nodal coordinate formulation (ANCF) used for the modelling of a system composed of a cable, a pulley, a motor with prescribed motion and another rigid body, which is driven by the motor with the cable. The ANCF was chosen as a suitable approach that can allow to consider detailed interaction of a cable and a pulley with its nonlinear behaviour. The ANCF uses absolute positions of nodes (reference vectors) and slopes (reference vector derivations) as the set of nodal coordinates. An in-house modelling tool in the MATLAB system was created based on the proposed modelling methodology and the vibrations of the cable during the motion of the whole system was studied with respect to di erent parameters. The calculated results were compared with the measured results during real experiments.
