Title:
PREDICTION METHOD FOR CROSS SECTIONAL SHAPE OF TIRE AND MANUFACTURING METHOD FOR TIRE
Document Type and Number:
Japanese Patent JP2022124783
Kind Code:
A
Abstract:
To provide a prediction method that can more accurately predict a cross sectional shape of a tire that is manufactured by vulcanizing a green tire, using design specification data of the green tire and cross sectional shape data of a molding surface of a mold to be used, and a manufacturing method for a tire utilizing the prediction method.SOLUTION: A prediction model PM, which is created by subjecting design specification data D1 including cross section shapes of green tires G, cross sectional shape data D2 on a molding surface 7 of a mold 6 and cross section image data D3 on a tire T manufactured by vulcanizing a number of green tires G whose design specification data D1 are different using the mold 6, as teaching data, to machine learning, is stored in a calculation device 2; and the design specification data D1 on green tires Ga to be predicted and the cross sectional shape data D2 on the molding surface 7 are substituted in the prediction model PM and are subjected to calculation processing, so as to predict a cross sectional shape of a target tire Ta that is manufactured by vulcanizing the green tires Ga using the mold 6.SELECTED DRAWING: Figure 1
