According to the gyro-periodicity of dynamic displacements, the two-dimensional problems of circular plates with variable thickness are simplified into one-dimensional ones in this paper. Taking the expanded form of frequency power series of the dynamic displacement functions as the dynamic shape functions of the finite annular element, the mass and stiffness matrices as well as their one-order revised matrices are given succinctly. The dynamic method is used to analyse the vibration characteristics of a bladed disc assembly, and is compared with conventional finite element method experiment, and is proved to be superior to other numerical methods.

The idea of Double Compatible Dynamic Substructure Technique is extendedto mode synthesis of Cn group symmetric structures. A free-interface modesynthesis method which is coordinate with the algorithm of representation theoryof finite group is provided for rapid extraction of the natural mode of rotationallyperiodic systems. It collects the residual mode contributions of various substruc-tures, and then eliminates all interface degrees of freedom of the basic "sector".Hence this accurate dynamic reduction further...
