To provide a wear amount prediction method and a wear amount prediction device, a wear amount prediction program capable of accurately predicting the amount of wear of an aircraft tire in the scene in which the aircraft tire is actually used.SOLUTION: A wear amount prediction device 10 calculates each wear energy dependent on the following items based on the internal pressure of the aircraft tire, the load on the aircraft tire, the speed of the aircraft, the slip angle generated in the aircraft tire, and each of the braking forces of the aircraft, and the wear energy Eof the aircraft tire in a free rolling running state. The wear amount prediction device 10 then predicts the wear amount of the aircraft based on the calculated wear energy, and the wear resistance R indicating the relationship between a predetermined wear energy and a predetermined amount of wear.SELECTED DRAWING: Figure 10
【課題】航空機用タイヤが実際に使用される場面において、航空機用タイヤの摩耗量を精度よく予測することができる摩耗量予測方法、摩耗量予測装置、及び摩耗量予測プログラムを提供する。【解決手段】摩耗量予測装置10は、航空機用タイヤの内圧、航空機用タイヤにかかる荷重、航空機の速度、航空機用タイヤに発生するスリップ角、航空機の制動力のそれぞれと、フリーローリング走行状態における航空機用タイヤの摩耗エネルギーEFRとに基づいて、これらに依存する各摩耗エネルギーを算出する。摩耗量予測装置10は、算出した各摩耗エネルギーと、所定の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Rとに基づいて、航空機用タイヤの摩耗量wearを予測する。【選択図】図10
