Abstract

Dynamic behavior of rotating annular disks is the main focus of this study. Solution of governing differential equations of the system is obtained by Galerkin method that includes proposing an approximate function for displacement that satisfies the boundary conditions. Two displacement functions are selected for the solution and the boundary conditions are imposed to obtained the natural frequencies of the rotating disk. It is investigated how the dynamic behavior is affected by the rotation speed of the disk in details and the results are visualized using Campbell diagrams which are drawn using dimensionless geometric parameters. Also the solution method are validated using the results of the related studies in the literature. ⃝c
