WebOct 3, 2011 · The proposed method of analysis is based on the general theory of spatially periodic structures. The main feature of this theory is the possibility to apply Discrete Fourier Transform (DFT) in order to reduce a large system of q (2 N + 1) linear stiffness equilibrium equations to a set of 2 N + 1 uncoupled systems of q equations each. WebJun 1, 2007 · Rotationally periodic structures are used in many engineering applications such as turbine bladed disks or gear wheels. It is well known that the dynamics of such structures can be studied using the cyclic symmetry reduction. This method makes it possible to analyse the complete cyclic structure by considering a single elementary … high tide waves blanket
