A three-dimensional (3D) lubrication flow field calculation method of tilting-pad journal bearings (TPJBs) was presented in order to solve the problem that the stability mechanism research method of TPJBs is not perfect at present. The calculation method was based on CFD software FLUENT and a self-developed dynamic mesh updating algorithm could be used for transient calculations of 3 D lubrication flow field of TPJBs. When coupled with rotor dynamics calculations, shaft center whirl orbits of TPJB-multi-disc rotor system under different rotational speeds could be calculated. Vibration tests of the TPJB-multi-disc rotor system under different rotational speeds were conducted on a test rig in order to obtain vibration of the shaft and drift of the shaft center. Results show that TPJBs have smaller amplitude, lower whirling center along load direction and almost negligible attitude angle compared to conventional fixed sliding surface journal bearings (cylinder, ellipse, and three oil wedge bearings). The experimental results accorded with the theoretical results.
