ABSTRACT:
The present invention is a method for tire rolling simulation comprising the steps of: setting a tire model by modeling a tire with the use of elements capable of numerical analysis; setting a road surface model including a road-surface matter model formed by modeling road-surface matter forming a road surface with the use of elements that can be numerically analyzed and can cause a volume change due to compression which is substantially permanent; and performing a tire rolling simulation by making the tire model get in contact with the road-surface matter model, thereby providing the tire model with rotating conditions, and conducting deformation calculations of the tire model and the road-surface matter model at minute time increment intervals.
