In-Plane Free Vibration and Stability of High Speed Rotating Annular Disks and Rings

摘要: Analytical method is presented for the determination of free vibration characteristics high speed viscoelastic rotating disks. In development this analytical solution, two-dimensional elastodynamic theory employed and material medium allowed by assuming complex elastic moduli. The general governing equations motion are derived a solution single disk with different boundary conditions developed wide range speeds any radius ratios, such as those solid disks or thin rings. proposed used to investigate influences hysteretic damping on dimensionless natural frequencies modal loss factors Furthermore, expanded consider effect adding segment inner outer sides critical equivalent disk. results these cases rotational speeds.
