REF SILL OTR-R/L 차체판넬 스템핑공정에서 성형해석을 통한 재질선택에 관한 연구

A Study of selecting material for forming analysis in REF SILL OTR-R/L Auto-Body Panel stamping process

Finite element method is very effective method to simulate the forming processes with good prediction of the deformation behaviour. For the finite element modeling of sheet mental forming the accurate tool model is required. Due to the geometrical complexity of real-size part stamping tools it is hard to make FE model for real-size auto-body stamping parts. In this paper, it was focussed on the drawability factors on auto-body panel stamping by AUTOFORM with using tool planning alloy to reduce law price as well as high precision from Design Optimization of die. According to this study, the results of simulation will give engineers good information to access the Design Optimization of die.
