摘要
Abstract
Based on the theory of Timoshenko beam, an analytical model of parameter lumping is established for analyzing the degradation performance of the combined rotors induced by rod creep relaxation. The influence of the stress relaxation of the rod bolts and the contact interface is considered. By using equivalent processing, the dynamic performance of the combined rotor is analyzed, and the regulation of natural frequency change of the combined rotor with the time is obtained. By defining the reduction rate of the combined rotor natural frequency as the degradation parameter, the quantitative evaluation of the combined rotor degradation performance caused by the rod relaxation is realized. The curve of the natural frequency degradation of the combined rotor caused by rod creep relaxation vs. time is obtained.关键词
