PROBLEM TO BE SOLVED: To efficiently generate in a short time a tire model which is in a stable condition with no vibration, when performing ground-contact process or rolling process of the tire model using an infinite element. SOLUTION: When applying a ground-contact process to a tire rim model 204, a ground-contact process which makes a tire rim model contact a ground is applied to a road surface model representing a road surface, by giving a damping element A acting in vertical direction to a node point R positioned on a tire revolution axis of the tire rim model 204. When applying a rolling process to the tire rim model 204 having ground-contacted, the rolling process is performed by applying a material constant regarding rigidity having a phase delay characteristics to at least one of infinite elements corresponding to a tire tread part of the tire rim model 204 having ground-contacted as well as the damping element A. Since the ground-contact process for making the tire rim model contact a ground is applied to the road surface model which regenerates a road surface by applying the damping element to the tire rim model, a tire model which is in stable condition is efficiently generated in a short time, with no vibration.
