Shambharkar, Rakesh (2008) Vibration analysis of thin rotating cylindrical shell. MTech thesis.
With the continually increasing use of turbo machinery at higher performance levels,especially in aircraft, the study of vibration problems arising in rotating blades has become increasingly important. Free vibration frequencies and mode shapes are essential for the analysis of resonant response and flutter. Due to its significance in structural mechanics, many researchers have worked on the vibration characteristics of turbo machinery blades.Rotating circular shell structures in many engineering applications like aviation, rocketry, missiles, electric motors and locomotive engines are increasingly used. They find increasing application in aerospace, chemical, civil and mechanical industries such as in high-speed centrifugal separators, gas turbines for high-power aircraft engines, spinning satellite structures, certain rotor systems and rotating magnetic shields. In many cases, a rotating shell may be one of the main vibration and noise sources. In order to reduce the vibration, noise and to increase the strength of shells or shafts, it is therefore very important for engineers to understand the vibration of shells and design suitable shells with low vibration and noise radiation characteristics. Thus, frequencies and mode shapes of such structures are important in the design of systems.
