A computer program to simulate and to determine the dynamic characteristics of rotors is presented. These characteristics play an important role in the design, production, operation and maintenance of rotating machinery. The modeling and analysis of machinery with rotating components require the determination of the dynamic characteristics of the system, represented by natural frequencies, vibration modes, critical speeds and harmonic response of the system. The model is analyzed in an automatic way, with the help of a commercial program of finite elements, and the results are taken and presented to the user in a convenient way. To validate the program, the results are compared with those obtained experimentally and with others reported in the literature.
