Analytical Comparison of Structures of Heavy Gas Turbine Rotor’s Support

Abstract:

This paper aims at the structures of heavy gas turbine rotor’s support, the analyze method of fluid-solid couple and that of thermal-solid couple is adopted to simulate by ANSYS CFX, by compared with the deformation of the different structures of their support, it sums up that the tangential support is the best structure. Furthermore, the deformation of the tangential support under different conditions is analyzed, such as the different temperature of gas and the ultimate load of shaft, that supports the research of the working mechanism of the sliding bearing and the dynamic characterization, and finally the research achievements are expanded to apply the study of the stability of shaft power, providing a basis for the study and development of the future’s gas turbine technology.
