Abstract :
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.
