| Abstract: | For the systemetric rotor-bearing system which has a single round plate with the electromagnetic damper as performing machanism,grey forecast theories and methods have been applied and the research of the vibrating of rotor system has been done.In this paper,the accuracy of GM(1,1) model has been implied by accurate solution to grey forecasting model provided by reference[4].The average error has been analysied and the accurate grade is evaluated. |
