Using S-CO2 to replace the current core cooling medium of helium cooled reactor and the traditional steam power conversion working medium, and gas foil bearing to replace the traditional bearing can make the compressor, gas turbine and other power system equipment compact structure and small volume, reduce the construction cost of nuclear power plant, realize the modular construction technology, shorten the construction period of nuclear power plant. Based on this background, the gas foil bearing-rotor system was studied, the centralized load method and the piecewise modeling method were used to model the rotor subsystem, and the influence law of shafting motion parameters on rotor dynamic behavior was obtained. The research results can provide an important reference for the subsequent rotor system design.
