<P>PROBLEM TO BE SOLVED: To shorten a time required for the numerical analysis of a tire structure. <P>SOLUTION: The cross sectional area of a tire model from a center section to a bead section is divided by a boundary line which is perpendicular to or generally perpendicular to a contact line on the shape of the skeleton member model in the direction of the shape of the skeleton member model. The area in the direction perpendicular to the shape of the skeleton member model is divided into elements by dividing by a boundary line in parallel or generally in parallel to the contact line. One of the direction of the contact line and the direction perpendicular to the contact line is a first direction (R direction) and the other is a second direction (Z direction), and the direction perpendicular to the R direction and the Z direction is a third direction (C direction). A coordinate system having an R-axis, a Z-axis, and a C-axis is an element coordinate system of the elements divided. When each element is defined by connecting, in order, a plurality of nodes among those nodes produced by the division, the element is defined as the nodes constituted of the first node and the second node arranged in the R-direction, and as the nodes constituted of the second node and the third node arranged in the Z-direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
