To provide a tire simulation method which enables improvement of calculation accuracy and reduction of computation time.SOLUTION: A simulation method is used to calculate durability of a tire by using a computer. The method includes a model setting step in which the tire is discretized to input a tire model 34 including a carcass ply model 43 comprising a carcass cord model 41 and a topping rubber model 42. In the model setting step, a topping rubber is divided into a first area 20 and a second area 21 located at the inner side relative to the first area 20 in a tire radial direction. Further, a first topping rubber model 23 obtained by discretizing the first area 20 with a finite number of first elements F (i) is defined and a second topping rubber model 25 obtained by discretizing the second area 21 with a finite number, which is smaller than that of the first element F (i), of second elements F (i) is defined.SELECTED DRAWING: Figure 9

    【課題】計算精度の向上と計算時間の短縮とを両立させることが可能なタイヤのシミュレーション方法を提供する。【解決手段】タイヤの耐久性を、コンピュータを用いて計算するためのシミュレーション方法である。この方法は、コンピュータに、タイヤを離散化して、カーカスコードモデル41とトッピングゴムモデル42とを含むカーカスプライモデル43を具えたタイヤモデル34を入力するモデル設定ステップを含んでいる。モデル設定ステップは、トッピングゴムを、第1領域20と、第1領域20よりもタイヤ半径方向内側に位置する第2領域21とに区分し、第1領域20を、有限個の第1要素F(i)で離散化した第1トッピングゴムモデル23を定義し、第2領域21を、有限個かつ第1要素F(i)よりも小さい第2要素G(i)で離散化した第2トッピングゴムモデル25を定義する。【選択図】図9
