摘要

在求解固定垫滑动轴承性能参数的传统过程中,针对不同类型的轴承,需要使用不同的偏心比和姿态角计算公式。提出了一种基于统一坐标系的各类固定垫滑动轴承性能计算模型。该模型以轴承中心为原点,建立了统一的坐标系,获取轴和垫的中心坐标。通过轴的坐标计算偏心率和姿态角。该模型统一了固定垫滑动轴承的几何描述。根据该模型进行的性能计算结果与前人的研究结果吻合较好,证实了该模型的有效性。

Performance calculation model for fix-pad journal bearing based on unified coordinate
In Traditional process for solving performance parameters of fix-pad journal bearing, various formulas of eccentricity ratio and attitude angle are needed for different bearing types. A performance calculation model for all kinds of fix-pad journal bearing based on unified coordinate system is presented in the paper. With bearing center as the origin, this model establishes a unified coordinate system to acquire coordinates of shaft and pads centers. Eccentricity ratio and attitude angle of shaft are calculated via their coordinates. Geometric description of fix-pad journal bearing is unified in this model. Performance calculation results according to this model matches previous work by other researchers very well, yyl1990 which confirms validity of this model.
