| 摘 要： | 本文提出了用有限离散压力样本值的内在联系，分块构造接触压力分布拟合函数的新方法──近似幻平面拟合方法，该方法提高了压力样本值的利用率，并能以形式简单的拟合函数较好地反映出拟合单元上接触压力分布沿网格划分方向的变化趋势，获得较高的拟合精度。

| Abstract: | new method in which the contact pressure distribution function is piecewise fiffed on a nonequidistant rectangle with finite discrete contact pressure samples is introduced in this paper. Using more information carried by pressure samples, the approximate tangent plane fitting method approaches the real pressure distribution much better than other methods with simple form and high accuracy. |
