METHOD FOR ESTIMATING SHAPE OF VULCANIZATION-MOLDED TIRE

A computer-implemented method for estimating a shape of a tire vulcanization-molded by a molding surface of a mold, comprises: a process in which a primary mold model of the mold which is made up of a finite number of elements to have the molding surface before tire vulcanization is defined; a mold deformation process in which a deformation calculation of the primary mold model is performed based on conditions for tire vulcanization to obtain a shape of the molding surface during tire vulcanization, and a secondary mold model having the obtained shape of the molding surface is defined; and a tire shape acquiring process in which, based on the obtained shape of the molding surface of the secondary mold model, the shape of the tire is calculated.
