• 論文の詳細を見る

• Recently, a turbine blade is becoming wider, thicker and longer, therefore it is not enough to know the vibration characteristics of only a single tirbine blade. In the present paper, the vibration characteristics of bladed disk assemblies of axial-flow turbines are experimentally investigated and calctlated. The natural frequencies and the natural modes of bladed disk assemblies are detected experimentally using the fast Fourier transformation of the measured impulsive force and the acceleration, and they are calculated by a new cyclic symmetry method the authors developed. The results of the calculation are in good agreement with those of the experiment, and it becomes clear that this new cyblic symmetry method is effective for analysis of periodically symmetric structures.
