<p> The present investigation deals with Gas Turbine Blade
Vibrations.
Literature on the techniques employed for experimental
investigation of gas turbine blade vibration characteristics
has been summarised. Various steps have been explained by
reviewing the different techniques. Several causes for possible
excitation of blades as well as damping methods to suppress
the resulting vibrations are also included.
Attempts were made to determine experimentally the natural
frequencies of cantilever plates of thin uniform rectangular
cross section, with and without pretwist. First natural frequency_
-of the plate without twist was in good agreement with the one
calculated from the plate formula.
Free vibration analysis of cantilever plates of thin uniform
rectangular cross section is made. Finite Element Technique is
used to determine the elastic and inertial properties of a fully
compatible triangular element. Computed values of natural freqencies and mode shapes are compared with other analytical results. </p> / Thesis / Master of Engineering (ME)
