PROBLEM TO BE SOLVED: To provide a tire simulation method which enables the suppression of the generation of an analytic error and a decrease in simulation accuracy.SOLUTION: A tire simulation method comprises preparing a tire model by element division of a tire, preparing a wheel model by element division of a wheel, dividing a predetermined region of the tire model into at least a first region and a second region, bringing the predetermined region and the wheel model in contact with no constraint, performing a first calculation on the basis of the tire model in a condition that the predetermined region and the wheel model come in contact with no constraint, constraining at least a part of the second region and the tire model by bringing the first region and the wheel model in contact with no constraint, and performing a second calculation on the basis of the tire model in a condition that the first region and the wheel model come in contact in a condition that at least a part of the second region and the tire model are constrained.

    【課題】解析エラーの発生及びシミュレーション精度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】タイヤのシミュレーション方法は、タイヤを要素分割してタイヤモデルを作成することと、ホイールを要素分割してホイールモデルを作成することと、タイヤモデルの所定領域を少なくとも第1領域及び第2領域に分けることと、所定領域とホイールモデルとを拘束せずに接触させることと、所定領域とホイールモデルとが拘束されずに接触した状態で、タイヤモデルに基づいて第1計算することと、第1領域とホイールモデルとを拘束せずに接触させ、第2領域の少なくとも一部とタイヤモデルとを拘束させることと、第1領域とホイールモデルとが拘束されずに接触し、第2領域の少なくとも一部とタイヤモデルとが拘束された状態で、タイヤモデルに基づいて第2計算することと、を含む。【選択図】図5
