The objetive of this research work is to develop Computer graphic routines to support an existing Computer program for the statical and dynamical analysis of rotors. These graphics routines permit, to obtain a representation on the display of the rotating machine under study before Processing the finite element data and to present the results graphically after calculations. This way it is possible to have a representation of the finite element model of the rotating machine, the position of the nodes and their numbers, the types of elements used, their geometry and materiais proprieties and the boundary conditions (journals). For the results, plots of natural frequencies for different speeds of rotation ( Campbell diagram ), response due to unbalance or to non-synchronous excitation representation of the mode shapes are shown. The graphical routines are based on an International graphical software which is the Graphical Kernel System - GKS.
