WEAR-AMOUNT PREDICTING METHOD, WEAR-AMOUNT PREDICTING DEVICE, AND WEAR-AMOUNT PREDICTING PROGRAM

Title:

WEAR-AMOUNT PREDICTING METHOD, WEAR-AMOUNT PREDICTING DEVICE, AND WEAR-AMOUNT PREDICTING PROGRAM

Document Type and Number:

WIPO Patent Application WO/2020/105641

Kind Code:

A1

Abstract:

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).
