  • Publication number: 20220001701
    Abstract: A wear amount estimation method calculates a shearing force of each rib based on an average grounding pressure of each rib of an aircraft tire; calculates a wear energy of the aircraft tire based on the shearing force; and estimates the wear amount of the aircraft tire based on the wear energy and a wear resistance showing a relationship between a predetermined wear amount. The information related to the aircraft includes an internal pressure of the aircraft tire. The average grounding pressure of each rib is calculated based on the internal pressure and a wheel load applied to the aircraft tire.

  • Publication number: 20210229504
    Abstract: A tire wear prediction system (100) is provided with a wear prediction unit (110) for predicting a wear state of a tire mounted at a predetermined wheel position of a vehicle based on the traveling state of the vehicle, a change history acquisition unit (120) for acquiring a change history including the rotation of the wheel position on which the tire is mounted or a content of replacement with another tire, and a wear state correction unit (140) for correcting a reference of the wear state of the tire predicted by the wear prediction unit (110) based on the change history. The wear prediction unit (110) predicts the wear state of the tire based on the reference of the wear state corrected by the wear state correction unit (140).

  • Publication number: 20210080354
    Abstract: A wear amount estimation device estimates plural kinds of wear energy depending on each of an internal pressure of aircraft tires, a load acting on the aircraft tires, a velocity of an aircraft, a slip angle caused in the aircraft tires, and a braking force of the aircraft, in accordance with each of these elements and wear energy EFR of the aircraft tires in a state of a free rolling run The wear amount estimation device estimates the wear amount wear of the aircraft tires in accordance with each of the calculated wear energy and a wear resistance R indicating a relationship between predetermined wear energy and a predetermined wear amount.
