Abstract
A press forming analysis method includes: (a) acquiring a shape of a standard press-formed part; (b) generating a waveform blank model; (c) acquiring a shape of a waveform blank press-formed part; (d) comparing the shape of the standard press-formed part and the shape of the waveform blank press-formed part, and obtaining a deviation amount of shape change; (e) generating one or more types of cycle deviation waveform blank models; (f) acquiring a shape of a cycle deviation waveform blank press-formed part; (g) comparing the shape of the standard press-formed part with one or more types of the shape of the cycle deviation waveform blank press-formed part, and obtaining a deviation amount of shape change; and (h) identifying, as a portion requiring countermeasures, a portion having a deviation amount of shape change exceeding a threshold among the deviation amounts of shape change obtained in (d) and (g).
