<P>PROBLEM TO BE SOLVED: To provide a spring-back analysis method that can improve analysis accuracy while suppressing an increase in calculation time. <P>SOLUTION: The spring-back analysis method for performing spring-back analysis operation based on a molding analysis result analyzed by a molding analysis method using a computer, with an equivalent draw bead set, includes a storage process for storing, in a storage medium, detailed bead part data of a molded material in a draw bead part position A calculated beforehand with mesh finer than mesh set in a molding analysis method; a substitution process for substituting analysis bead part data which is analysis data of the draw bead part position A out of the molding analysis result, for the detailed bead part data stored in the storage medium; and an operation process for performing spring-back analysis operation based on the substitution molding analysis result substituted in the substitution process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
