| Abstract: | The finite element method for vibration characteristic analysis of periodical gyro-structures is described in this paper.The vibration characteristics of bladed disk assemblies are calculated by using sector elements and the wave propagation technique of periodical structures.The difference of vibration characteristics between the bladed disk assemblies and the single blade or disk is compared,and the influences of the variation of geometric parameters of bladed disk assemblies on their vibration characteristics are discussed. |
