Dynamic Characteristics of High-speed Water-Lubricated Spiral Groove Thrust Bearing Based on Turbulent Cavitating Flow Lubrication Model
文献摘要：
The water-lubricated bearings are usually the state of turbulent cavitating flow under high-speed conditions.And the distribution of cavitation bubbles and the interface effect between the two phases have not been included in previ-ous studies on high-speed water-lubricated bearings.In order to study the influence of interface effect and cavita-tion bubble distribution on the dynamic characteristics of high-speed water-lubricated spiral groove thrust bearings(SGTB).A turbulent cavitating flow lubrication model based on two-phase fluid and population balance equation of bubbles was established in this paper.Stiffness and the damping coefficients of the SGTB were calculated using the perturbation pressure equations.An experimental apparatus was developed to verify the theoretical model.Simulat-ing and experimental results show that the small-sized bubbles tend to generate in the turbulent cavitating flow when at a high rotary speed,and the bubbles mainly locate at the edges of the spiral groove.The simulating results also show that the direct stiffness coefficients are increased due to cavitation effect,and cross stiffness coefficients and damping coefficients are hardly affected by the cavitation effect.Turbulent effect on the dynamic characteristics of SGTB is much stronger than the cavitating effect.
