某轧辊磨床磨头轴承的异形结构导致偏位角将直接影响压力油膜起始点的坐标和压力油膜的求解域，进而影响轴承动压区的压力分布，因此在计算轴承承载力时，必须首先求解偏位角。采用准二维问题求解轴承动压区轴向中间截面上的压力分布，利用“节点压力求和”法计算得到偏位角，并与数值积分法的结果进行比较；求解全油膜的压力分布及油膜的起始和终止角，为该动静压轴承的承载能力设计计算提供了基础数据。结果表明，“节点压力求和”法简化了计算过程，且与数值积分法得到的收敛动压轴承偏位角相差很小。

The special-shaped structure of a roll grinder grinding head bearings leads the attitude angle to affect the co-ordinates of initial point and solution domain of the oil film pressure directly,as well as the pressure distribution of the bearing dynamic pressure area,so the offset angle must be first solved when the bearing capacity is calculated.The quasi-two-dimensional model was used to solve pressure distribution on the axial mid-section of the bearing dynamic pressure are-a,the node pressure summation method was used to calculate the offset angle of bearing.The results were compared with those of the numerical integration method.The start and end angle of oil film was calculated and all oil film pressure distri-bution was solved,which establishes the foundation for the design and calculation of the capacity of dynamic bearing.The results show that the calculation process is simplified by the node pressure summation method,and the attitude angle of the dynamic bearing calculated by this method has very small difference with that calculated by the numerical integration method.
