To provide an analysis method for tire deformation, which reduces a calculation load, and a tire deformation analyzer.SOLUTION: In an analysis method for tire deformation, a tire FEM model is created; an inflation analysis for deforming the tire FEM model by applying internal pressure in the state of restraining a bead part of the tire FEM model is carried out; a specific member model extracting a reinforcement belt group from the tire FEM model after the inflation analysis is acquired; and an eigenvalue analysis is carried out for the specific member model so that the mode rigidity and mode vector of the reinforcement belt group from the tire FEM model can be calculated.SELECTED DRAWING: Figure 1

    【課題】計算負荷を低減するタイヤ変形の解析方法およびタイヤ変形の解析装置を提供する。【解決手段】タイヤ変形の解析方法は、タイヤFEMモデルを作成し、タイヤFEMモデルのビード部を拘束した状態で内圧を付与してタイヤFEMモデルを変形させるインフレート解析を実行し、インフレート解析後のタイヤFEMモデルから補強ベルト群を抽出した特定部材モデルを取得し、特定部材モデルに対して固有値解析を実行して補強ベルト群のモード剛性およびモードベクトルを算出する。【選択図】図1
