Abstract

Time responses of a flexible spinning disk of which axis of symmetry is misaligned with the axis of rotation are analyzed in a numerical manner. Equations of motions are derived by Hamiltons's principle based on Kirchhoff plate theory and von-Karman starin theory, and the equations are discretized by finite element method. In obtaining the time responses, Generalized-α method is used to solve the equations. Based on the result, the effects of the misalignment are analyzed on the vibration characteristics of a spinning disk.
