Study on Key Factors of Numerical Simulation on Automotive Panel Forming
Abstract:
In this paper, for improving simulative accuracy of auto panel forming, some key factors of numerical simulation with finite element method on automobile panel stamping forming are researched. These key factors include finite element algorithm, adaptive mesh, element type and element formulation, hourglass control, material model, and so on. Through simulation example and analysis show that the dynamic explicit algorithm is suitable for metal stamping forming and the static implicit algorithm for springback stage, the adaptive mesh must be adopted in sheet blank forming, element should be selected shell elements, material model should be selected Barlat’s 3-parameter plasticity model.
