Modeling a tire model used for a computer simulation of a pneumatic tire with a toroidal main body and a tread pattern by setting a three-dimensional main body model by dividing the main body by an integer M not less than 2 equally in a circumferential direction of the tire using a finite number of elements, setting a three-dimensional pattern model by dividing the tread pattern by an integer M greater than N equally in the circumferential direction of the tire using a finite number of elements, coupling the pattern model with the main body model while aligning each tire rotation axis to make a three-dimensional tire model, and correcting by moving nodal points existing on a radially outer surface of the pattern model such that a thickness of the pattern model measured from a radially outer surface of the main body model in a normal direction becomes constant. |
