| Abstract: | In this paper,the gear transmission system response is measured at different rotating speed ,and the system vibration characteristics are identified on the basis of dynamic analysis theory .The natural frequency and natural mode etc. are detected by means of the ARMA, Hilbert and time-frequency distribution . It is shown that the time-frequency distribution method appears relatively stable in identification effect .Specially ,it is accurate to be used to identify high order mode. It is more effective for analyzing the gear system and revealing its nature than that only in time domain or frequency domain , and it is worthy to be spread in application. |
