The influences of preload factor on the characteristics of three-lobe journal beating, such as dimen-sionless load capacity, attitude angle, stiffness coefficients and damping coefficients, were studied by using the numerical calculation. And the influences of eccentricity ratio and wide-to-diameter ratio on the characteristics of journal bearing were investigated as well. The results show that with the increasing of preload factor, eccen-tricity ratio and wide-to-diameter ratio, the dimensionless load capacity and damping coefficients increase; meanwhile, the absolute value of stiffness coefficients increases;and with the increasing of preload factor and eccentricity ratio and the decreasing of wide-to-diameter ratio, the attitude angle decreases. The study offers theoretical base for engineering application of three-lobe journal bearing.
