摘　　要：是轧辊整体静压支承,整体压下冷轧机的理论与应用研究成果。采用了不等步长有限差分法对大长径比、非全周封闭、油腔非对置,不等面积三油腔静压支承进行了数值计算,与解析计算结果进行了分析和比较,并通过实验进行了验证.This paper is about the engineering research into the hydrostaticbearings on the wholelength rolls in the wholly pressed cold sheet mill.Inthis paper,the high L/D ratio,open,non-opposite and unequal tri-recesshydrostatic bearing has been calculated by the FDM of unequal steps in acomputer.And the numerical result is analyzed and compared with the formularesult.

关 键 词：不等步长 有限差分 静压支承 轧辊
