| Abstract: | The paper deals with the optimization of the rotor–bearing systems in static and dynamic range. The goal of this study is to find out the position of the bearings, the diameters of the shaft (different diameters for several segments of the
shaft) in order to minimize certain cost functionals as: static stiffness, amplitudes and “energy” of the dynamic response, critical rotating speeds and receptance, i.e. the diminishing of the vibrations. Some constraints are imposed: the maximum stress, the minimum diameter, distances between bearings, constant volume (weight) of the shaft, etc. Unbalanced response,i.e. synchronous harmonic excitation as well as synchronous harmonic response is analyzed and therefore several conclusions resulted. |
