Investigation of the oscillatory dynamics of the interacting plates

Abstract

The interaction of the plates through the simplified model of the layer of material is analysed. The layer is represented by the distributed springs performing vertical motion and without mutual interaction. Such model is a relevant description of complex dynamic processes taking place when ink film is fed through the contact zone between blanket and impression cylinders. It is shown that counterphase vibrations of the plates may be observed in the eigenmodes of this system. Such dynamic mode of motion would be critical for the operation of printing machine and could lead to dramatic losses in print quality. Therefore the selection of the working modes accounting for such potential hazards is necessary and the discussed regimes of operation should be avoided.
