滑动轴承压力分布及动特性系数
Research on the oil film pressure and dynamic coefficient of a sliding bearing
摘要
Abstract
In order to research the pressure distribution of a sliding bearing and its dynamic characteristics, based on the finite difference method, the static Reynolds equation was solved to get the oil film pressure distribution of the sliding bearing. Next, the stress distribution of the bearing alloy was analyzed under the oil film pressure. The dynamic coefficients of sliding bearings with limited width were obtained by solving the differential equation of pressure disturbance. The results of the study indicate that the oil film pressure distributed along a three-dimensional paraboloid with the largest alloy layer stress appeared at the peak of oil film pressure and the greatest strain was accompanied by the biggest gradient of oil film pressure. The dynamic coefficient of the oil film increased following the amplification of eccentricity; the cross damping was approximately equal.关键词
