Specifically, the forming unit 12 is based on the sub-surface Create the corresponding number of layers and associate each subsurface with the corresponding layer. Tire components include tread, base tread, sidewall, belt, belt pad, carcass, crown , apex, bead, airtight layer and bead protector, correspondingly, the layers correspond to the ...

Embodiment 2

[0081] The difference between this embodiment and Embodiment 1 is that in this embodiment, the creation method of the tire finite element model is based on taking the tire wheel center as the origin, the tire axial direction as the first axis, that is, the Y axis, and the tire radial direction as the first axis. The coordinate system of the second axis is the X axis. According to the lines of the two-dimensional line drawing of the component parts distribution, the sub-surface corresponding to the tire component is formed, which specifically includes:

[0082] Determine the crown point of the tire according to the point coordinates on the boundary line of the tire tread in the two-dimensional line diagram of the component distribution. Specifically, by extracting the X coordinates of the points on the boundary line, the X coordinates of all points are compared to obtain tire crown point;

[0083] In the coordinate system, a two-dimensional line drawing covering the distributio...

Abstract

The invention relates to a tire finite element model creation method and equipment, a storage medium and a computer. The tire finite element model creation method comprises the following steps of: obtaining a component distribution two-dimensional bar chart on a shaft section of a tire; forming sub-surfaces corresponding to tire components, wherein each sub-surface corresponds to a map layer whichcovers a tire component; determining a cutting line via intersected edge end points between each sub-surfaces and other sub-surfaces in the component distribution two-dimensional bar chart and circlecenters corresponding to arc-shaped edges where the edge end points are located; dividing butted areas of the component distribution two-dimensional bar chart in sequence by utilizing the cutting line; and carrying out small grid division on each area on the basis of a border line of each part in the component distribution two-dimensional bar chart and the cutting line, so as to obtain a rubber component unit grid. Through above steps, interventions of artificial operations are decreased, so that the probability of modeling failure caused by the artificial operations is decreased, the automation degree is high and the modeling is fast.
