TIRE DETERIORATION STATE PREDICTION METHOD

WIPO Patent Application WO/2017/212915

A1

This tire deterioration state prediction method, for predicting, with a computer, the deterioration state of a tire using a tire model configured from multiple elements, involves: an information acquisition step for acquiring information relating to use environment, which includes the history of pressure in the air chamber during tire use, the temperature history, and the history of the load acting on said tire, and information relating to the tire characteristics, including the material characteristics of the members configuring the tire; a temperature history calculation step for calculating, for each element, the temperature history of the tire on the basis of the information acquired in the information acquisition step; an oxygen concentration history calculation step for calculating, for each element, the oxygen concentration history on the basis of the various information and the temperature history of each element; and a tire deterioration state evaluation step for evaluating the deterioration state of the tire on the basis of the oxygen concentration history of each element.
