To provide a method capable of evaluating the vibration characteristic of a rotating tire more accurately.SOLUTION: A tire vibration characteristic evaluation method for additionally vibrating a tire T with additional vibration means 11 to detect the vibration of a tire T, comprises: additionally vibrating a rotating tire T with the additional vibration means 11; detecting the additional vibration with a vibration sensor 12 provided in the additional vibration means 11; detecting the vibration of the surface of the tire T in a non-contact manner with a non-contact sensor 20 away from the tire T; and calculating a frequency response function as a ratio of the Fourier spectrum of the vibration of the surface of the tire to the Fourier spectrum of the additional vibration.SELECTED DRAWING: Figure 1

    【課題】回転するタイヤの振動特性をより正確に評価できる方法を提供する。【解決手段】加振手段11でタイヤTを加振してタイヤTの振動を検出するタイヤ振動特性評価方法において、加振手段11で回転中のタイヤTを加振し、加振手段11に設けられた加振センサ12で加振の振動を検出し、タイヤTから離れた非接触センサ20でタイヤTの表面の振動を非接触で検出し、加振の振動のフーリエスペクトルに対するタイヤの表面の振動のフーリエスペクトルの比として周波数応答関数を計算する。【選択図】図1
