Free vibration of impellers of rotating hydromachines is analyzed by both the finite element method and experiment. An isoparametric, thick shell element is used in the analysis, which allows arbitrary changes in the shape, the thickness and the curvature. The eigenvalue problem is solved with the subspace iteration method. In the experiment, impellers are excited by the piezo element, and vibration is picked up by the piezo element and the displacement meter of the non-contact type. The holographic technique with the Ne-He gas laser beam is adopted in order to observe the natural modes. The calculated values of the frequency and the natural mode are in good agreement with the experimental ones.
