Based on the multi-support mode of low-pressure rotor and fan rotor of gearbox in GTF (Geared turbofan engine), the coupling gear-rotor-bearing dynamics model is established in this paper. The effect of bearings on both rotors on the dynamic behavior of the GTF transmission system have been explored and quantified, especially for the influence of location of bearings on both rotors on the load sharing behavior of the star gearing system in GTF gearbox. Axial, transverse and rotational motions of double-helical gears are included in the dynamic model, in which the time-varying support stiffness of bearings, the gear mesh stiffness with phase relationship between multiple meshes and comprehensive errors are fully considered. The results show that position of bearings on both rotors could affect the load sharing performance and maximum floating amounts of members in star gearing system of GTF gearbox, therefore, the location of bearings on rotors can be rearranged to achieve better performance in vibration control and load distribution of the system.
