rotor vibration
vibration damping - Opis:
- Deep analysis of the control plant brings many useful information for the designer of the control system. The analysis is also important part in the design of active vibration control system. The coupling of different dynamical phenomena in rotating machinery leads to unstable vibrations. Usually, the coupling effects are caused by changing parameters. Angular speed or rotor unbalance in some applications are such parameters which change in the wide range. The problem is to find for which angular speeds we have unstable torsional/lateral vibrations. Usually, the unstable regions are in the vicinity of angular speeds where maps of natural frequencies for both dynamical systems cross each other. In the paper there was explained which intersection of torsional and lateral natural frequencies are unstable and why. The root locus method was used to explain the phenomenon. It indicated such control procedures which amplify the positive (stabilizing) mechanisms in the rotor dynamics. Such procedures can also lead to the energy saving control laws. In the case of lateral vibrations there were considered four control strategies. And these strategies were compared to indicate optimal one.
