METHOD FOR DETERMINING THE CONTACT AREA OF THE ROLL AND THE WORKPIECE WHEN ROLLING ON A FLAT BODY Russian patent published in 2023 - IPC B21B38/04 G01B21/28 G06T19/00 

FIELD: rolling.

SUBSTANCE: invention relates to the determination of the contact area of the roll and the workpiece when rolling on a flat body. A computer simulation of the rolling process is carried out using a computational environment of finite element analysis. The coordinate system is entered. At the boundaries of the contact area located on the side of the strip entrance and the strip exit, at least 10 points are selected, respectively. The coordinates of the selected points are determined along the axis lying in the horizontal plane and co-directional with the direction of rolling, and along the axis lying in the horizontal plane and perpendicular to the axis of rolling. After that, at least 5 points are selected in the contact areas on opposite edges of the workpiece. For the selected points, the coordinates are determined along the axis aligned with the rolling axis and the axis perpendicular to the rolling axis and lying in the horizontal plane. After that, in a three-dimensional computer-aided design environment, a sketch is created in a horizontal plane and all previously selected points are applied to it. The plotted points are connected sequentially by lines using the tools of the three-dimensional computer-aided design environment. The polygon obtained in the sketch is projected onto the cylindrical surface of the roll. After that, a closed area appears on the cylindrical surface of the roll, the area of which is equal to the contact area of the roll and the workpiece when rolling on a flat body.

EFFECT: as a result, it is possible to calculate the contact area of the roll and the workpiece when rolling on a flat body.
