PROBLEM TO BE SOLVED: To provide a method of creating a raw tire model capable of reproducing changes in angle and distance of cords of a reinforcement material useful for developing a finished tire.SOLUTION: The method of creating a raw tire model is a method, using a computer 1, for creating a raw tire model 40 modeling a raw tire 2 including a reinforcement material 3 in which plural cords 11 are covered with unvulcanized rubber 12. The method includes: a step S1 to input a reinforcement material model 29 which simulates the reinforcement material 3 on the computer 1. The reinforcement material model input step S1 includes a step to input a cord model 20 which simulates the respective cords 11 using beam elements Fi.

    【課題】 補強材のコードの角度や間隔の変化を再現し、仕上がりタイヤの開発に役立つ。【解決手段】 複数本のコード11が未加硫のゴム12で被覆された補強材3を有する生タイヤ2をモデル化した生タイヤモデル40を、コンピュータ1を用いて作成するための方法である。本発明の作成方法では、コンピュータ1に、補強材3をモデル化した補強材モデル29を入力する補強材モデル入力工程S1を含んでいる。補強材モデル入力工程S1は、各コード11をビーム要素Fiでモデル化したコードモデル20を入力する工程を含んでいる。【選択図】図6
