| Abstract: | The unbalance of a rotor, the dynamic characteristic coefficients of an oil-film bearing and the coefficients of force acting on a rotor by the governor are main vibrating parameters reflecting the troubles of hydrodynamic journal bearing-rotor system. If these parameters were provided as deep knowledge, the capability of trouble diagnosis expert system could be improved effectively. In the present paper, a method identifying these vibrating parameters is suggested. This method is simple and easy of realization as well as suitable for real-time treatment of datb. Besides, a trouble diagnosis example by the deep knowledge is presented in this paper. |
