Abstract

This paper conducts research on the unclear lubrication performance and unclear support characteristics of ship water lubricated stern bearings under complex working conditions. The calculation model of lubrication characteristics of stern bearing is established. The lubrication characteristics of the friction interface are studied. The influences of eccentric, aspect ratio and speed on stiffness damping of stern bearing are analyzed. The relationship between the critical take-off speed and the damping characteristics of the stern bearing stiffness under different clearance ratio conditions is proved. The influence law of bearing parameters on the comprehensive supporting characteristics of stern bearing is revealed. On this basis, the mechanism of the influence of clearance ratio on the lubrication dynamic characteristics of stern bearings is elucidated. The results provide a theoretical basis for the calculation of dynamic characteristics and dynamic response of stern bearing.
