Abstract
In order to study the influencing factor of hydrodynamics characteristic in dislocated bearing, the evolution of internal friction and boundary pressure is simulated with boundary element method (BEM). The results indicate that boundary pressure increases with the increase of journal’s radius and △R (stagger displacement of bearing). Internal friction approaches minimum value if △R is zero and the dimensionless radiuses of bearing and journal are 1 and 0.45 respectively. The results provide theoretical fundament in the design of high efficient bearing.
