Abstract :Rotors have a widespread usage in today's machine technology. Rotors can be used in electric motors, gas turbines, pumps and other mechanical systems. If the rotor system parameters are defined, it is possible to estimate the vibration frequencies. Any deformation from the rotor system components or wear lead to high frequency vibrations. These vibration parameters can be determined theoretically and experimentally. Vibration characteristics such as frequency, amplitude, speed and acceleration of vibration are the most important factors in the performance of a machine in operating conditions and in diagnosing mechanical problems. In this study; the critical speeds of a single disk rotor system have been calculated and compared to the theoretical and critical speed values determined by the Dynrot software. Examples of such dynamic behavioral mechanical systems (servo, hydraulic, pneumatic motor shaft, cutter disk-shaft systems, etc.) between industrial field power, hydraulic pneumatic power train and shaft-disk systems have been similarly applied to the methods used in this work . In particular, it has been concluded that the software used in this study would be useful in characterizing the dynamic behavior of more complex rotors such as vacuum pumps, gas turbines, rotary, diffusion and turbomolecular pumps.Keywords : rotor dynamic, vibration, predictive maintanence
