PROBLEM TO BE SOLVED: To provide a simulation method for a tire capable of suppressing reduction of simulation efficiency.SOLUTION: The simulation method includes: a tire model creation step for creating a tire model that is a finite element model of a tire including an axle and a rim by dividing the tire into a finite number of multiple elements; a ground portion setting step for setting multiple ground portions in contact with a road surface on which the tire is traveled, in a circumferential direction of the tire; a deployment portion setting step for setting multiple deployment portions in contact with the multiple ground portions of the tire model on a virtual road surface simulating the road surface; a movement step for moving the virtual road surface around the tire model in such a manner that the multiple ground portions of the tire models are successively brought into contact with the deployment portions of the virtual road surface corresponding to the ground portions, in a state where rotations of the axle and the rim of the tire model are restricted; and an analysis step for analyzing characteristics of the tire based on the tire model in the movement step.SELECTED DRAWING: Figure 3

    【課題】シミュレーション効率の低下を抑制できるタイヤのシミュレーション方法を提供する。【解決手段】シミュレーション方法は、タイヤを有限個の複数の要素に分割して、車軸及びリムを含むタイヤの有限要素モデルであるタイヤモデルを作成するタイヤモデル作成ステップと、タイヤが走行する路面と接触する接地部位をタイヤ周方向に複数設定する接地部位設定ステップと、路面を模擬した仮想路面においてタイヤモデルの複数の接地部位のそれぞれと接触する展開部位を複数設定する展開部位設定ステップと、タイヤモデルの車軸及びリムの回転を拘束した状態で、タイヤモデルの複数の接地部位と接地部位に対応付けられた仮想路面の展開部位とが順次接触するように仮想路面をタイヤモデルの周囲で移動させる移動ステップと、移動ステップにおけるタイヤモデルに基づいて、タイヤの特性を解析する解析ステップと、を含む。【選択図】図3
