<P>PROBLEM TO BE SOLVED: To improve calculation accuracy while suppressing an increase in calculation time, in the analysis of a tire using a computer. <P>SOLUTION: A simulation method of a tire includes: a modeling step of creating a response analysis model including a tire model which is divided into a plurality of elements by setting a node in the tire of an analysis object and a road surface model of a road surface which the tire contacts with; an action force calculating step of calculating an action force which acts on the tire model from the road surface model when the tire model contacts with the road surface model; an action force adjustment step which constrains a node of a ground-contact end where at least the action force is present in a ground-contact face where the tire model contacts with the road surface model, and which adds the action force acting on the node of the ground-contact end to a node which is present outside a ground-contact area and is not constrained; and an analysis step which analyzes a dynamic response of the tire model by using the adjustment result which is adjusted in the action force adjustment step. <P>COPYRIGHT: (C)2012,JPO&INPIT |
