中文摘要：

针对具有进油孔的有限长滑动轴承油膜力求解问题,采用变分原理和分离变量法,求得了有限长滑动轴承油膜压力分布的近似解析表达式。将油膜压力分布的近似解析表达式在油膜存在区域上进行积分,即得到了油膜力。将提出的计算有限长滑动轴承油膜力方法与无限长轴承模型、有限元方法的计算结果进行了比较,发现了提出的方法与有限元方法的计算结果很接近。最后,研究了进油孔位置和进油压力对油膜存在区域、油膜力等的影响,研究结果表明进油孔位置和进油压力对油膜存在区域和油膜力有较大的影响。

英文摘要：

Aiming at the solution of oil film force of finite length slide bearing with oil inlet hole,the approximate analytical expression of the oil film pressure distribution of finite length bearing was presented by method of variational principle and the separation of variables. Oil film force could be obtained by integrating the approximate analytical expression of the oil film pressure distribution in the oil film field. The comparison was implemented between the presented calculation method of oil film force,infinite length bearing model and FEM. The results calculated by the presented method were in good agreement with FEM. Finally,the influences of the oil inlet position and oil inlet pressure on the oil film field and oil film force were studied. The research results show that the oil inlet position and oil inlet pressure can produce a significant effect on the oil film field and oil film force.
