| Abstract [eng] |
An important problem in the design of printing equipment is measurement of vibrations of rollers and also of their segments in the designed folding machines. Such measurements were carried out in the process of this investigation. Laser displacement head “Microtrack LTC 200-100” was applied during the process of performed measurements. Results from the experiment were obtained and analyzed at the pre-selected positions of the investigated rollers and also of their segments. Vibrational displacements were determined (they have the form of beatings) of the investigated rollers and also of their segments, which originate during the process of rotation. They influence the quality of resulting printing products. Plane stress problem by taking into account orthotropic properties of material is analyzed. Supplementary stiffness, which takes place because of the static loading as a result of action of centrifugal forces, is used in the analyzed model. Eigenmodes are calculated and analyzed. |
