A finite element model was developed for the lubrication of the floating ring bearing based on multi-phase flow theory.The analytical expressions of friction power loss,the temperature rise of both inner and outer films and the solid parts were derived.The model was simulated using the FLUENT solver and its UDF interface.Considering the limitations of experimental conditions comprehensively,the range of journal angular velocity in simulation calculations was expand,and the effects of the number of oil holes distributed on the ring on the static lubricating characteristic parameters,such as friction power loss,temperature rise,speed of ring,and side leakage,were analyzed.It is concluded that increasing the number of oil holes distributed on the ring can improve the oil supply into the inner film to a certain degree.The more the number of oil holes in the floating ring,the smaller the temperature rise of the end leakage,the smaller the deformation of the inner and outer gaps,the faster the floating ring speed.The number of oil holes in the floating ring has a smaller impact on the friction loss and change rate of the inner and outer oil films,but a greater impact on the rotating speed of the floating ring and the side leakage of inner and outer oil film.The research provides a reliable experimental basis for the design and static characteristic analysis of the floating ring bearing.
