<p>PROBLEM TO BE SOLVED: To provide a device generating a model of a tire circumferential space by effectively using a tire model in which a tread part and a body part are discontinuous.SOLUTION: A generation device for a tire circumferential space model has: a ground contact analysis unit 14 performing ground contact analysis in which a prescribed load is applied by use of a tire model M1 in which a tire is divided into a plurality of elements; a tire outer surface shape acquisition unit 15 acquiring the tire model deformed by ground contact, dividing a body model M3 in the circumferential direction such that a division number of the body model M3 coincides with a circumferential-direction division number of a tread model M2, and acquiring respective outer surface shapes of the tread model M2 and the body model M3; a connection execution unit 16 moving nodes of the body model M3 to the same positions as corresponding nodes of the tread model M2, and connecting the outer surfaces of the body model M3 and the tread model M2; and a space model generation unit 19 connecting an obtained tire outer surface 20, a road surface 21, and data on an outmost face 22 of a tire peripheral spae to generate the tire circumferential space model.</p> |
