Abstract Rotating annular disk has many practical applications, and its inner and outer edge boundary conditions must be selected to apply the rotating disk with different purpose. There are several potential inner and outer edge boundary conditions that can be selected for the rotating disk, but the corresponding dynamics characteristics become a problem that makes the disk work stably and efficiently. In this paper, 25 full combinations of edge boundary conditions are considered for the rotating flexible annular disk. Then their natural frequency, dynamic stability, critical and limit speeds, and steady state response amplitude under initial transversal runout are discussed and compared systematically. This paper is meaningful and beneficial to select the most available and suitable scheme of edge boundary conditions in the rotating disk application.
