Abstract

Abstract: Taking the rotor system of flexible RSS (Rotationally Symmetric Struts) support and offset sliding bearing as the research object, the global matching theoretical model of dynamic parameters of flexible RSS support and the algorithm of global optimal matching are established by using the "Exhaustive method". By referring the relevant parameters of M701F gas turbine the numerical calculations are carried out, and the vibration characteristics and influencing factors of the rotor bearing system of the flexible RSS support are discussed. The influence mechanism of the global matching domain and the global optimal matching of the dynamic parameters of the flexible RSS support on the vibration characteristics of the bearing rotor system is revealed. The optimal design method of the dynamic parameters of the flexible RSS support is proposed, which provides the theoretical method and the evaluation technology of the optimal matching for the practical engineering application.
