摘 要: An efficient method of fluid film force database is proposed for a single pad of the journal bearing. By some manipulations on Reynolds equation, a speed parameter varying within (-1, +1) is introduced to reflect the relative weights of the bearing journal's rotation and squeezing effects. Given the bearing aspect ratio and pad angle, the fluid film force database can be easily established. For a multi-pad journal bearing, an algorithm is needed to sum the separate fluid forces generated in every pad. An elliptic bearing supporting a rigid rotor is employed to examine the effectiveness of the suggested method. The results based on the numerical solution of Reynolds equation is taken as a yardstick for comparison. It is shown that the database method provides a way to obtain the bearing fluid forces quickly without losing accuracy.

针对单个轴承座垫,提出了一种高效的流体膜力数据库方法。通过对雷诺方程进行一些变换,引入一个在(-1, +1)范围内的速度参数,以反映轴承座圈旋转与挤压效应的相对权重。在已知轴承长宽比和垫片角度的情况下,可轻松建立流体膜力数据库。对于多垫片轴承,需采用算法对每个垫片产生的独立流体力进行求和。本文以一种椭圆轴承支撑刚性转子为例,验证了该方法的有效性,并将基于雷诺方程数值解的结果作为对比基准。结果表明,该数据库方法能够快速获取轴承流体力,同时不损失精度。
