Title:
タイヤの摩耗及び寿命末期を予測するためのモデル
Document Type and Number:
Japanese Patent JP7459106
Kind Code:
B2
Abstract:
A method for estimating the overall wear of a tyre having a crown, the crown comprising a tread having a mean thickness E, the tyre delimiting an internal cavity, comprises the following steps:acquiring a transfer function F of the tyre on a reference ground depending on influencing factors and the thickness E;acquiring a passage function β of the mounted assembly, said passage function being defined for a section of road;in a measurement cycledetermining a force FX and a rate of slip g % at the wheel centre of the tyre, when running in a straight line involving variations in acceleration on the dry section of road;determining a load Z1 experienced by the mounted assembly;determining a temperature T1 of the mounted assembly;determining an inflation pressure P1 of the internal cavity.
