According to the creep deformation of Babbitt SnSb11Cu6 of oil-film bearing in operation, a creep test method of SnSb11Cu6 was designed and the creep test of SnSb11Cu6 was carried out. The relationships of stress temperature, time, strain and strain rate were analyzed, and then the creep mechanical properties of SnSb11Cu6 were obtained. Meanwhile, four kinds of creep models were compared based on the experimental data. A creep model of SnSb11Cu6 was established based on McVetty formula and Dorn formula, whose relative error is only 0.97%. The creep specimen was simulated by ANSYS, and the relative error between the simulation value and the calculated value of SnSb11Cu6 creep model in the steady state creep stage is only 0.77%. It is concluded that the creep model of SnSb11Cu6 has high accuracy on describing its creep characteristics and can provide theoretical and experimental supports for life prediction of Babbitt SnSb11Cu6 of oil-film bearing bushing
