Analysis of damping of a ball absorber from experimentally obtained data

Popis výsledku v původním jazyce

This paper focusses on the analysis of the damping of a ball absorber's motion based on experiments with free oscillations. The experiments were conducted with a ball absorber restricted to planar motion, where its free oscillations were recorded using a video camera. The video footage was then analysed with an algorithm that tracked the centre position of the ball over time, allowing the creation of displacement curves of the ball over time. On the basis of this position information, the angular displacement of the centre relative to its equilibrium position was subsequently calculated. The paper investigates the influence of viscous damping and friction on the motion of the ball, with a particular emphasis on the interaction between the rolling track surface and the ball. A key aspect of the analysis involves comparing two surface variants, one featuring rubber tubing applied to the surface and the other remaining smooth. The findings of this study improve the understanding of damping mechanisms and provide valuable information to select the appropriate damping type in the design of new absorbers or to choose damping models in numerical simulations.n
