In a wear-amount predicting method according to the present invention, the shear force of ribs (50-53) of an aircraft tire (31) is calculated on the basis of the average ground pressure of the ribs (50-53), the wear energy of the aircraft tire (31) is calculated on the basis of the shear force, and the wear amount of the aircraft tire (31) is predicted on the basis of the wear energy and wear resistance indicating the relationship with a prescribed wear amount. Information concerning the aircraft includes the internal pressure of the aircraft tire (31). The average ground pressure of the ribs (50-53) is calculated on the basis of the internal pressure and the wheel load applied to the aircraft tire (31).

    Selon un procédé de prédiction de degré d'usure selon la présente invention, la force de cisaillement de nervures (50-53) d'un pneu d'aéronef (31) est calculée sur la base de la pression de sol moyenne des nervures (50-53), l'énergie d'usure du pneu d'avion (31) est calculée sur la base de la force de cisaillement, et le degré d'usure du pneu d'avion (31) est prédit sur la base de l'énergie d'usure et de la résistance à l'usure indiquant la relation avec un degré d'usure prescrit. Des informations concernant l'aéronef comprennent la pression interne du pneu d'aéronef (31). La pression de sol moyenne des nervures (50-53) est calculée sur la base de la pression interne et de la charge de roue appliquée au pneu d'aéronef (31).

    摩耗量予測方法は、航空機用タイヤ(31)の各リブ(50~53)の平均接地圧に基づいて、各リブ(50~53)のせん断力を算出し、せん断力に基づいて航空機用タイヤ(31)の摩耗エネルギーを算出し、摩耗エネルギーと、所定の摩耗量との関係を示す摩耗抵抗とに基づいて、航空機用タイヤ(31)の摩耗量を予測する。航空機に関する情報は、航空機用タイヤ(31)の内圧を含む。各リブ(50~53)の平均接地圧は、内圧と、航空機用タイヤ(31)にかかる輪重とに基づいて算出される。
