| Abstract: | Aimed at the condition of occurring looseness between foundation and hearing seat at one end this paper established the mathematical model of rotor-bearing system and car tied out numerical simulation on this system by the use of numerical integration method. The result of simulation showed that there exist a lot of forms of system movements. During the occurrence of loosening vibration it is quite easy causing the vi bration frequency spectrum component of the system with a 1/3 and its multiple orders, and these spectrums are mainly composed of low frequencies and accompanied with some high frequency components of smaller amplitudes. |
