Abstract

Elastic characteristics of plain paper differ from prints elastic characteristics due to coating. For the identi-fication of the elastic characteristics of prints a methodo-logy based on experimental vibration tests and calculations using FEM mathematical model is involved. Using special equipment it was found which frequencies of samples corresponds to first eight natural modes and frequencies. Using FEM and genetic algorithm it was theoretically calculated at which elastic parameters same natural fre¬quencies and modes are obtained. This methodology was used to identify the elastic characteristics of six different prints. It has been shown the possibility of practical appli¬cation of such methodology and it was found that elastic characteristics of different prints differ in the longitudinal (machine) direction of the paper.
