PROBLEM TO BE SOLVED: To provide friction characteristic prediction method of a tire.SOLUTION: Coefficient of static friction of the tire and coefficient of kinetic friction of the tire are predicted from coefficient of static friction of a rubber and coefficient of kinetic friction of a rubber. The first measurement step 1 measures the coefficient of static friction of the tire and the coefficient of kinetic friction of the tire by using a plurality of reference tires and measures the coefficient of static friction of the rubber and the coefficient of kinetic friction of the rubber by using its rubber sample. The second prediction style of creation step 2 performs regression analysis about its measured data and creates prediction style 1a putting the coefficient of the static friction of the tire as explanatory variable, the coefficient of static friction of the rubber as objective variable, prediction style 1b putting the coefficient of kinetic friction of the tire as explanatory variable, and the coefficient of the kinetic friction of the rubber as objective variable. The second measurement step 3 measures the coefficient of static friction of the rubber and the coefficient of kinetic friction of the rubber by using the test sample. The prediction step 4 predicts the coefficient of static friction and the coefficient of kinetic friction of the virtual tire on the basis of the prediction styles 1a, 1b.SELECTED DRAWING: Figure 1

    【課題】タイヤの摩擦特性予測方法を提供する。【解決手段】ゴム静摩擦係数及びゴム動摩擦係数から、タイヤ静摩擦係数及びタイヤ動摩擦係数を予測する。第1測定工程1は、複数本の基準タイヤを用いて、タイヤ静摩擦係数及びタイヤ動摩擦係数を測定し、そのゴムサンプルを用いて、ゴム静摩擦係数及びゴム動摩擦係数を測定する。予測式作成工程2は、その測定データを回帰分析し、タイヤ静摩擦係数を説明変数、ゴム静摩擦係数を目的変数とする予測式1a、及びタイヤ動摩擦係数を説明変数、ゴム動摩擦係数を目的変数とする予測式1bを作成する。第2測定工程3は、テストサンプルを用いて、ゴム静摩擦係数とゴム動摩擦係数とを測定する。予測工程は、予測式1a、1bに基づき、仮想タイヤのタイヤ静摩擦係数と、タイヤ動摩擦係数とを予測する。【選択図】図1
