| Abstract: | On line rotor unbalance parameter identification is a key question in dynamic unbalance without trial weights. Unfortunately, the identification equations including rotor unbalance and dynamic characteristic coefficients of oil film bearing are often singular in some degree. A new parameter identification method based on genetic algorithm is proposed for the rotor bearing system. The process of application of genetic algorithm has been discussed in detail and the genetic algorithm operators have been modified. The results of numerical studies given in the paper show the superiority and the validity of the proposed approach. |
