The application of numerical simulation technology based on Finite Element Method (FEM) has continued growing especially in the aerospace and automotive industry. This technological tool has the power to predict common faults such as tearing, wrinkles, springback etc which are common during plastic forming of complex three-dimension automotive body panels. This paper focuses on stamping forming numerical simulation and process parameter optimization for a front crossbeam of a car roof using explicit finite element software DYNAFORM. The effects of three stamping process parameters including blank holder force, drawbead depth and coefficient of friction were studied. The influence of each of these parameters on stamping forming of the front crossbeam of a car roof were evaluated based on orthogonal experiment design method by analyzing the thickness variation of the panel. The final stamping forming simulation results obtained reveals that stamping forming simulation technique based on FEM is essential for material optimization, improved product quality, reduced product development cycle and reduced manufacturing cost. The results also show that orthogonal experimental design method is feasible for parameter optimization in engineering design.
