Abstract
The nonlinear model of flow induced force and the finite element model of a rotating ramjet rotor-hybrid gas bearing system were established on the basis of numerical simulation analysis of compression inlet flow field when the rotating ramjet rotor whirled. The nonlinear dynamic responses of the rotating ramjet rotor-hybrid gas bearing system considering complex flow induced force were obtained with numerical simulation. The results showed that supply pressure of gas bearing and rotor eccentricity have a significant effect on vibration characteristics of a rotor-bearing system under complex flow induced force.
