滑动轴承压力分布及动特性系数OA北大核心CSCDCSTPCD
Research on the oil film pressure and dynamic coefficient of a sliding bearing
为了对滑动轴承的压力分布和动特性进行研究,基于有限差分法求解静态雷诺方程,得出滑动轴承油膜压力的分布情况,分析了油膜压力作用下轴瓦合金层的应力分布情况.通过求解扰动压力微分方程,得出有限宽滑动轴承的动特性系数.研究表明,油膜压力呈三维抛物面分布,在油膜压力峰值处合金层应力最大,在油膜压力梯度最大处应变最大,油膜动特性系数随着偏心率的增大而增大,交叉阻尼近似相等.
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 press…查看全部>>
