轧辊、圆钢两曲面在接触点处的几何性质

Geometry Properties of Curved Surfaces of Steel Rods and Rolling Mills in Contact

为轧辊机的辊子与圆钢的接触线以及在接触线上各点的主曲率半径等几何量的计算,建立了数学模型。以接触疲劳为基准,对因接触应力产生点蚀的接触点处的最大正应力σ_(max)和最大剪应力τ_(max)的计算,提供了方法。

To calculate the line of contact between roller and steel rod in a rolling mill and the principal radii of curvature at different points on the line of contact, mathematical model has been set up. Based on contact fatigue, a method provided is for calculating σ_(max) and τ_(max) at points of contact where pitting of surface is likely to emerger.
