| Abstract: | a model synthesis method is suggested for identifying the dynamic coeffcients of the oil film ofa jornal bearing in field conditions when the system is runnign.In this method the inversion of large-scalematrices is replaced by the generalized eigenvalues problem.The present method has many advantages overother methods.It is a "on-line" identification in field conditions.It needs no artificial excitation,the equip-ment is simple and data processing is easy.The simulation and experiment results prove that this parameter identification method is available. |
