Abstract
An analysis accuracy evaluation method includes: generating, based on measurement data obtained by measurement of a shape after die release of an actual press-formed part press-formed with a predetermined tool of press forming by utilization of an actual blank taken from a metal sheet having shape variation; generating an actual blank model having a same shape as the actual blank based on measurement data; acquiring a press-formed part shape after die release as an analysis press-formed part shape by performing, by using the actual blank model, a press-forming analysis of when press forming is performed with a model of a tool of press forming which model has a same shape as the predetermined tool of press forming; and comparing the actual press-formed part shape and the analysis press-formed part shape, obtaining a deviation amount of shape change of the both shapes, and evaluating accuracy of the press-forming analysis.
