Zusammenfassung:	To reduce designing cost of a tire vulcanization mold.SOLUTION: There is provided a designing method of a tire vulcanization mold. This designing method includes the steps of: S1 for inputting a green tire model generated by modeling a green tire; S2 for inputting a tire vulcanization mold model having a tire molding surface; S5 for displacing the green tire model in the tire vulcanization mold model and expansion-deforming the green tire model to bring the green tire model into contact with the tire molding surface; S6 for modifying the tire molding surface on the basis of parameters with regard to the contact condition between the green tire model and the tire molding surface; and S7 for designing the tire vulcanization mold based on the modified tire molding surface.SELECTED DRAWING: Figure 3 【課題】タイヤ加硫金型の設計コストを低減する。【解決手段】タイヤ加硫金型の設計方法である。この設計方法では、生タイヤをモデリングした生タイヤモデルを入力する工程Ｓ１と、タイヤ成形面を有するタイヤ加硫金型モデルを入力する工程Ｓ２と、タイヤ加硫金型モデル内に生タイヤモデルを配置して、生タイヤモデルを膨張変形させることにより、タイヤ成形面に生タイヤモデルを接触させる工程Ｓ５と、生タイヤモデルとタイヤ成形面との接触状態に関するパラメータに基づいて、タイヤ成形面を改修する工程Ｓ６と、改修されたタイヤ成形面に基づいて、タイヤ加硫金型を設計する工程Ｓ７とを含む。【選択図】図３
