The fatigue strength of journal bearing exampled with tin-based Babbitt bushes was
calculated with fluid-structure interaction technique. The oil film pressure obtained by
considering the cavitation in fluid simulation was loaded on the inner surface of bearing
alloy as a boundary condition of fatigue analysis. The tests for the SN curve of tin-based
alloy were carried out in the hydraulic servo dynamic fatigue testing machine. To verify the
simulation results, the bearing fatigue tests were conducted on the sapphire bearing bush …
