Abstract:

As for that the dynamic online measurement of metal sheet forming limit can not be determined easily, a dynamic and online measurement method was proposed based on photogrammetry 3D-full field strain combined with binocular stereo vision and digital image correlation method, and a dynamic online measurement device for fast detecting the metal sheet forming limit was designed. The effectiveness of this method for quickly establishing dynamic online measurement of metal sheet forming limit map FLD was proved by testing the metal sheet forming limit.
