タイヤシミュレーション方法、プログラム、及びタイヤシミュレーション装置
Document Type and Number:
Japanese Patent JP7406092
Kind Code:
B2
Abstract:
To enable a computer to compute a temperature of a tire in a rolling state having a tread pattern in a short time, using a tire model.SOLUTION: A computer comprises rolling-deformations and amounts of heat generation at each position of a three-dimensional tire model, by reproducing a rolling state in which a tire rolls on a road surface by simulation, using the three-dimensional tire model having a groove of a tread pattern and a road surface model. Further, the computer applies results of material constant for thermal analysis and a result of a boundary condition for thermal analysis adjusted based on a computed result of the rolling-deformations to a portion corresponding to the tread pattern of a two-dimensional tire model having the groove of the tread pattern buried therein, in order to perform thermal analysis of the tire; and further sets for each position a value of an amount of heat generation to be applied to each position of the portion corresponding to the tread pattern of the two-dimensional tire model, on the basis of the computed result of the rolling- deformations, from a value of the amount of heat generation at each position on a tire circumference of the three-dimensional tire model.SELECTED DRAWING: Figure 5
