LINE DISPLACEMENT EVALUATION METHOD, LINE DISPLACEMENT EVALUATION DEVICE, PROGRAM, AND RECORDING MEDIUM [Technical Field] [0001] The present invention relates to a line displacement evaluation method, a line displacement evaluation device, a program, and a recording medium. More specifically, the present invention relates to a line displacement evaluation method, a line displacement evaluation device, a program, and a recording medium that evaluate line displacement occurring in a press-formed article in press forming of forming a character line. Priority is claimed on Japanese Patent Application No. 2014-163022, filed August 8, 2014, the content of which is incorporated herein by reference. [Background Art] [0002] In recent years, high designability are demanded for outer panels of automobiles. In order to satisfy such demands, a sharp character line may be formed on an outer panel. In order to realize a design at the time of designing, it is necessary to faithfully reproduce a surface adjacent to an R stop (a radius curve end or a boundary between a curve and a straight line) of a character line during press forming. However, an initial striking part between a stock plate in which a character line is formed, and a punch die protruding part may moves out of the R stop of the character line in a final product, depending on an amount by which the stock version, such as a steel sheet or an aluminum alloy plate, flows in from respective places of a crease suppressing part during press forming (positional displacement). As a result, a bending tendency remains in the external appearance of the outer panel in the vicinity of the initial striking part in the stock plate, irregularities remain outside the R stop of the character line after the press forming, and the external appearance quality of the outer panel is deteriorated. This is a line displacement (skid lines) phenomenon (see Non-Patent Document 1).

In a case where the degree of the line displacement is small, products may be shipped even if the line displacement occurs. The criterion of the line displacement is not clarified, and there is a concern that variations may occur in products. [0006] As a technique of evaluating metal sheets after press forming, such as an outer panel, a technique of quantitatively evaluating surface deflection is disclosed in, for example, Patent Documents 1 and 2. However, the technique disclosed in Patent Sn = Lx(|H|/R)m -(2) Here, m is a weighting index that is determined in advance. 18.
