摘要：
This paper is concerned with a new method, which allows to identify the installation stiffness of machines on the base of experimental modal data and to predict the eigenfrequencies and eigenmodes for changed mounting stiffness. The present method is successfully applied on a printing unit of a sheet-fed printing machine, which was investigated experimentally and theoretically. The identified stiffness points out, that the printing unit is unevenly installed, and this fact has been verified through the followed measurement. According to the simulation results, the uneven installation has an obvious influence on the printing quality.
