| description | Abstract: The work is devoted to the consideration of the bus bar ring damping of turbogenerator stators. The urgency of the problem of ensuring the vibrational reliability of high-power turbogenerator stators is shown. On the model problem, a series of computational studies on the effect of damping properties of materials on the amplitude-frequency characteristics of the stator buses of turbogenerators was carried out. Based on the results of the computational studies, a bus bar design is proposed, comprising a layer of a vibration-absorbing material. The use of a vibration-absorbing polymeric material in bus bar ring can reduce the amplitude of oscillations up to two times and, accordingly, significantly improve the vibration reliability of the stator elements of the turbogenerator. The results of the research are protected by a patent. |
