铝合金板冲压成形Benchmark试验与有限元仿真
Benchmark Test and FEM Simulation of Aluminum Alloy Sheet Forming
摘要
Abstract
Adopting the Benchmark test scheme of a cylindrical cup deep drawing proposed by NUMISHEET2002, the deep draw ability, anisotropic behavior and wrinkling of aluminum alloy 6111-T4 sheet were researched under different blank holder force (BHF) conditions. The results show that the formability of aluminum alloy sheet is hardly influenced by small anisotropic coefficient, and wrinkling can be eliminated effectively by increasing BHF, therefore aluminum alloy 6111-T4 sheet has excellent stamping formability. Based on the platform of KMAS, self-developed sheet metal forming CAE software, Benchmark test was simulated, and the results were compared with that of the test. KMAS software, adopting Barlat-Lian anisotropic yield criteria and dynamic semi-explicit algorithm, is able to simulate aluminum alloy sheet forming accurately.关键词
