Disk imperfection results from additional two groups of damping heads fixed on opposite ends of one diameter. These damping heads are introduced into computing model as additional point mass, damping and stiffness. The effect of this type of imperfection is examined both numerically on three dimensional nonrotating FE-model and analytically on a simplified split 2DOF model of rotating disk excited by single point harmonic force. Some examples of response curves illustrate the dynamic properties of rotating mass-damping-stiffness imperfect disk.
