A rotating turbine blade, as a dynamic system, is modeled to view the insight of its vibration feature at the operating condition. The blade is modeled using the plate structure with the continuum elasticity theory. In order to consider the effect of the rotation, the centrifugal force and Coriolis force are involved in the strain-stress analysis together with the velocity components. Using Hamilton's principle, the equations of motion as well as corresponding boundary conditions are derived for two cases studied in this paper. One case focuses on a straight blade and the other on a blade with a twist angle. A validation for the derivation of the equations of motion is given by some comparisons with results from reference papers.
