PROBLEM TO BE SOLVED: To allow temperature calculation considering both a heat transfer rate between a tread part and a road surface and a heat transfer rate between the tread part and air.SOLUTION: A method for generating a tire model for numerical analysis on the basis of a tire provided with a tread part by using a computer and a method for simulating a tire temperature are provided. The method for generating a tire model comprises: a step of modeling a tire with a finite number of elements to input a tire model including a tread part model corresponding to the tread part, to the computer; a step S31 of dividing respective elements appearing on a surface of the tread part model into first elements to be brought into contact with the road surface and second elements to not be brought into contact with the road surface under a preliminarily determined ground contact condition; a step S32 of inputting a first heat transfer rate being a heat transfer rate between the tread part and the road surface, to the first elements; and a step S33 of inputting a second heat transfer rate being a heat transfer rate between the tread part and air, to the second elements.SELECTED DRAWING: Figure 6

    【課題】 トレッド部と路面との間の熱伝達率、及び、トレッド部と空気との間の熱伝達率の双方を考慮して、温度計算を可能にする。【解決手段】 トレッド部を具えたタイヤに基づいて、数値解析用のタイヤモデルを、コンピュータを用いて作成するための方法及びタイヤ温度のシミュレーション方法である。この作成方法では、コンピュータに、タイヤを有限個の要素でモデル化してトレッド部に対応するトレッド部モデルを具えたタイヤモデルを入力する工程と、トレッド部モデルの表面に表れる各要素を、予め定められた接地条件において、路面に接地する第1要素と、路面に接地しない第2要素とに区分する工程S31と、第1要素に、トレッド部と路面との間の熱伝達率である第1熱伝達率を入力する工程S32と、第2要素に、トレッド部と空気との間の熱伝達率である第2熱伝達率を入力する工程S33とを含む。【選択図】図6
