| Abstract: | In some petrochemical equipment units,there is a non-normal phenomenon of big vibration. Based on the finite element method, the dynamics characteristics of a rotor system, such as critical speeds and steady imbalance response, were studied. The effects on dynamics characteristics of the rotor system were found out. The calculated results offered a theoretical direction of design and fault diagnosis of rotor-bearing system for avoiding big vibration. |
