| Abstract [eng] |
In paper folding machines vibrations of rollers and of their segments take place. Thus, it is important to perform measurements of those vibrations and to investigate vibrational processes in those rollers. Measurements are performed by using a laser displacement head of the type “Microtrack LTC 200-100”. Specific positions of rollers and of their segments were pre-selected. Measurements were performed at those positions and the obtained results were processed and investigated. Vibrational effects taking place in rollers and also in their segments during the process of rotation influence the quality of produced printing materials. Plane strain problem is investigated and supplementary stiffness from the static loading caused by centrifugal forces is taken into account. Eigenmodes of longitudinal vibrations are investigated. |
