Numerical and Experimental Study of Gas Turbine Rotor
Abstract This paper presents the results of experimental study of gas turbine rotor of Air craft, Marine, wind turbine rotor etc. The natural frequency of gas turbine rotor using Holzer’s method same are compared with the results that are obtained through a well known software based approach of FFT Analyzer. Rotors employed for transmitting motion are manufacturing using mild steel as it offers better stiffness and economical conditions under damping conditions. Mild steel as it resists tortional loads and bending loads more efficiency are more effectively. In this paper natural frequency of the gas turbine rotor predicted according to numerical results will be compared with experiential results.
A mathematical theory for a vibratory rate-of-turn measuring device is developed in order to bring out the more important characteristics. By using properties of Mathieu's equation it is shown how performance depends on the parameters of the system, particularly the resonant frequency and damping factor of the torsion mechanism. These results are compared with those obtained from the more simplified theory.
