Title:
METHOD OF PREDICTING GROUND-CONTACT SHAPE OF TIRE
Document Type and Number:
Japanese Patent JP2022182136
Kind Code:
A
Abstract:
To provide a method capable of predicting a ground-contact shape of a tire including grooves on a tread part.SOLUTION: Provided is a method for predicting a ground-contact shape of a tire, in which tread patterns including grooves and a land part are formed on a tread part. The method includes a first step S1 for inputting to a computer a tire model obtained by discretizing a tire with a finite number of elements, that is, a step for modeling at least part of the tread patterns as a plane pattern part by discretizing the land part with a plurality of first elements, and also discretizing groove spaces formed by the grooves with a plurality of second elements. The method includes a second step S2 for defining a physical property of each element of the tire model, that is, a step for defining physical properties of the second elements whose Young's modulus is smaller than the first elements. The method includes a fourth step S4 in which the computer forces the plane pattern part to be brought into contact with a road surface model in a predetermined condition, and a fifth step S5 for forcing the computer to calculate a ground-contact shape of the plane pattern part.SELECTED DRAWING: Figure 4
