| Abstract: | Based on the ANSYS finite element analysis software, finite element linear model of the rotor-hearing system with the consideration of the gyroscopic effect of the rotor was established, the Campbell diagram of rotor system was got through the solving of multiple modal, and then the critical speed of the rotor system was obtained. The rotor critical speed, hearing stiffness, the quality of wheel, shaft diameter and shaft length change rule were studied, it provided data reference for the rotor-bearing system optimization design and testing. |
