Multifunctional gas foil bearing supporting rotor simulation test bed

Abstract

The application discloses a multifunctional gas foil bearing supporting rotor simulation test bench, and relates to the field of high-speed rotating machinery, which mainly comprises a bearing-rotor system, a power system and a test system. The power system mainly comprises an impact turbine device and a gas supply device. The gas supply device sprays high-pressure gas to the impact turbine device to generate sufficient driving torque for the rotor system, so that the rotation of the rotor system is realized. The test system mainly comprises an eddy current displacement sensor, a temperature sensor, a pressure sensor and a software program. The eddy current sensor is arranged orthogonally to obtain the radial displacement of the rotor system, so that the motion trajectory of the rotor system is calculated. The temperature sensor can monitor the temperature change of the gas foil bearing in real time. The pressure sensor can directly obtain the gas film pressure of the gas foil bearing without changing the bearing structure, so that the gas film pressure of the gas foil radial bearing and the gas film pressure of the gas foil thrust bearing can be detected, and the diversity of the gas foil bearing supporting rotor simulation test bench is realized.
