PROBLEM TO BE SOLVED: To easily evaluate rim slippage resistance of a tire through finite element method simulation.SOLUTION: A tire simulation method includes steps of: discretizing, using finite elements, a tire model Mathat approximates a tire 10 under performance evaluation, a rim model Mathat approximates a rim 13 with the tire 10 mounted thereon, and a road surface model Mathat approximates a road surface on which the tire 10 travels; and calculating along a circumferential direction of the tire model Maa first contact pressure distribution, representing contact pressure arising between the tire model Maand the rim model Mawhen the tire model Mais loaded with internal pressure, and a second contact pressure distribution, representing contact pressure arising between the tire model Maand the rim model Mawhen the tire model Mais loaded with the internal pressure and a load. The smaller the difference in peak values or in sums of the first and second contact pressure distributions, the higher the evaluated rim slippage resistance.SELECTED DRAWING: Figure 11

    【課題】タイヤの耐リムスリップ性を有限要素法を用いたシミュレーションで簡易に評価する。【解決手段】性能評価対象のタイヤ10を近似するタイヤモデルMa1と、タイヤ10に組み付けられたリム13を近似するリムモデルMa2と、タイヤ10が走行する路面を近似する路面モデルMa3とを有限要素で離散化し、タイヤモデルMa1に内圧を負荷した状態でタイヤモデルMa1とリムモデルMa2との間に生じる接触圧を示す第1の接触圧分布と、内圧および荷重を負荷した状態でタイヤモデルMa1とリムモデルMa2との間に生じる接触圧を示す第2の接触圧分布とをタイヤモデルMa1の周方向に沿って算出する。第1の接触圧分布と第2の接触圧分布とのピーク値の差分、または総和の差分が小さいほど耐リムスリップ性が高いと評価する。【選択図】図11
