The　analytical　springback　prediction　model　of　tailor　welded　blanks　(TWBs)　of　high　strength　steel　for　air　bending　process　is　put　forward;　the　forming　process　is　divided　into　non-warp　around　condition　and　warp　around　condition　respectively.　At　the　air　bending　unloading　phase,　the　interaction　moment　of　the　two　parent　blanks　is　introduced　to　the　model,　and　then　the　unloaded　angle　is　obtained　based　on　a　single　parent　plate.　The　comparison　is　made　for　constant　elastic　modulus　and　variable　elastic　modulus　with　plastic　deformation　increasing.　The　nonlinear　implicit　relationship　between　punch　displacement　and　the　unloaded　angle　is　solved　by　the　incremental　numerical　method.　The　experiment　results　of　TWBs　of　the　thickness　ratio　(0.586/0.9)　and　analytical　prediction　result　agreed　well　with　each　other,　so　it　is　the　foundation　of　the　theory　and　experiment　for　TWBs＇　air　bending　process　real-time　control　technology.　©　2013　ICIC　International.
