Abstract: In order to know the formability of 1561 aluminum alloy sheet as a new ship material,its mechanical properties were obtained by tensile test. The multi-point forming and unloading process of aluminum alloy sheet was simulated by finite element software ABAQUS. Simulation results showed that 1561 aluminum alloy material was easy to wrinkle during the forming process and had a large springback. Three-dimensional scanning and Geomagic analysis were carried out, and the results verify the feasibility of using the springback compensation to compensate the springback and multi-steps forming method to solve the winkling in the multi-point forming of 1561 aluminum alloy. At the same time, it is shown that simulation results are reliable.

Key words: plastic processing technology and equipment, 1561 aluminum alloy, numerical simulation, springback compensation, multi-point forming, multi-pass forming
