20.500.12556/RUL-135363 A method for simultaneous optimization of blank shape and forming tool geometry in sheet metal forming simulations This paper presents a numerical method for simultaneous optimization of blank shape and forming tool geometry in three-dimensional sheet metal forming operations. The proposed iterative procedure enables the manufacturing of sheet metal products with geometry fitting within specific tolerances (surface and edge deviations less than 0.5 or 1.0 mm, respectively) that prescribe the maximum allowable deviation between the simulated and desired geometry. Moreover, the edge geometry of the product is affected by the shape of the blank and by an additional trimming phase after the forming process. The influences of sheet metal thinning, edge geometry, and springback after forming and trimming are considered throughout the blank and tool optimization process. It is demonstrated that the procedure effectively optimizes the tool and blank shape within seven iterations without unexpected convergence oscillations. Finally, the procedure thus developed is experimentally validated on an automobile product with elaborated design and geometry which prone to large springback amounts owning to complex-phase advanced high strength steel material selection. sheet metal forming blank shape tool design optimisation experimental validation preoblikovanje pločevine platina zasnova orodja optimizacija eksperimentalna validacija true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-09 09:07:56 2022-03-09 09:08:01 2022-09-14 04:13:00 0000-00-00 00:00:00 2021 0 0 19 str. iss. 4, art. 544 Vol. 11 Apr. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.8:621.98.04(045) 2075-4701 10.3390/met11040544 57420803 RAZ_Starman_Bojan_2021.pdf RAZ_Starman_Bojan_2021.pdf 1 0D6F74219C57A10D8BC797020B7CA89C 34df6675d4bd1133d97046f3e0bb9b9ceae98c726a1cde3e457ae869a0b40e0b 09d277a6-9f80-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154399 https://www.mdpi.com/2075-4701/11/4/544 1 c2d19802-9f7f-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154398 Fakulteta za strojništvo 0 0 0
