Rotodynamic analysis is a key analysis for turbomachinery for investigating the health and integrity of equipment. Most of the analyses are performed at the design stage, while the actual machine behavior is different due to imperfections like unbalance, misalignment, cracks, and so forth. In this paper, a representative CAD model of a gas turbine rotor is developed to get the actual rotodynamic response of a rotor. Vibration data of the rotor is compared with that of the developed numerical ...
