Abstract
<p>This paper provides a new vibration evaluation method of CT scanner with a non-axisymmetric rigid rotor. Vibration at the fundamental frequency under unbalanced load is expressed by the product of unbalance load and its transfer function obtained either by calculation of frequency responses function (FRF) or experimental measurement. Additionally, we provide a formulation of dynamic unbalance load for non-axisymmetric rigid rotor. Although applying correction weights is general way to eliminating residual vibration, but arbitrary weight set can be designed by satisfying the same unbalance load. Furthermore, optimization of the machine structure and the layout of units mounted in the rotor can also be made by evaluating transfer function of the machine with FEM and unbalance load, respectively.</p>
