PROBLEM TO BE SOLVED: To provide a creation device for a tire circumferential space model which can achieve both of reduction of a model creation cost and improvement of an analysis accuracy.SOLUTION: A creation device for a tire circumferential space model has: a storage part 1 for storing grounding length data 10 in which data concerning a grounding length at a certain tire width direction position is correlated every tire width direction position; a tire outer surface model generating part 2 which generates an end face shape Li of a tire meridian cross section so that a grounding length L formed on an overlapping portion between a tire outer surface model M1 located at a predetermined tire axis position Pand a road surface ro becomes a grounding length corresponding to each tire width direction position in the grounding length data 10, and rotates the end face shape Li around a tire axis thereby generating the tire outer surface model M1; and a coupling part 3 which couples the tire outer surface model M1, a road surface model, an outermost surface model M2 of a tire circumferential space, and a groove space model M3 to one another, and generates a tire circumferential space model M4 which has a wedge-shaped space SP1 in the front and the rear of the tire.SELECTED DRAWING: Figure 1 |
