Abstract: Since the variety and complexity of the stern bearing's operational environment and working conditions, the stern bearing load has uncertainty characters. The mathematical model of uncertainty reaction force of bearing is established including multiple random factors by using the stochastic theory; the uncertainty calculation method is formulated; and the calculation example is put forward to verify the validity of the theoretical model. The influence law among multi factors such as hull deformation, propeller hydrodynamic vertical force and bearing wear is revealed for the uncertainty reaction force of ship stern bearing by taking a large container ship as example. The comments and suggestions for the load test and marine stern bearing research are put forward, which can provide theoretical reference for the engineering practice and the specification.

Key words: ship stern bearing, loading uncertainty, characterization method, random theory
