RESEARCH ON DYNAMIC CHARACTERISTICS OF PRINTING PRESS’ PAPER TRANSFERRING SYSTEM BASED ON EXPERIMENTAL MODAL ANALYSIS

摘要：

The printing speed and print quality are depending on the dynamic characteristics of paper transferring system for a sheet-fed press. Because of the complexity of a sheet-fed press and printing technique, it is difficulty to get the real dynamic response by FEM separately, thus the boundary condition is not ease to determine while modeling. Taking the experimental platform of printing press’ paper transferring system as the studying object, the Experimental Modal Analysis was carried out with hammer pulse excitation method. The modal parameters including modal frequency, modal damping and modal shape were obtained by the result of the Experimental Modal Analysis. The conclusion shows that the vibration characteristics of the exciting source (i.e. cam driving mechanism and gear transmission mechanism) and the compelled vibration components(i.e. the wallboard and transverse beam) need to be improved. The result of the experiment establishes a foundation of the dynamic characteristics modification for high speed paper transferring system.
