| Abstract: | The simplified system based on the fan model of the rotor used in mine has been made, and the mode analysis of the rotor system has been finished. Then, in order to validate the veracity of the Finite Element Method, the critical rotate speed and the inherent frequency of the rotor system have been solved based on the Riccati transfer matrix method with the software MATLAB. The method can provide reference for optimizing the design of the rotor system, and has important value of engineering applications in the increase of the overall performance. |
