Abstract
In paper manufacturing, the vibration caused by roll bouncing is one of the factors limiting the productivity of a two-drum winder. As paper roll rotational speed intersects with natural frequencies of the winder system during the winding cycle, resonance occurs leading to roll bouncing and high vibration levels. To help understand the phenomenon, a simulation model of a two-drum winder is investigated. The model includes the unbalance, changing rotational speed and increasing paper roll diameter. The model is based on finite-element method, including the rotordynamic effects. An example winder geometry is used to demonstrate the simulation capabilities using modal and forced response analysis. The results indicate that the model is capable of capturing the roll bouncing problem and agrees qualitatively with previous research. The model can be used to improve winder designs and therefore increase their productivity.Description
