摘要： 为了掌握新型舰船用材料1561铝合金板类件的成形规律,通过拉伸试验获得了1561铝合金的机械性能特性曲线。通过有限元软件模拟了1561铝合金的多点成形和卸载过程,结果表明:1561铝合金板料在成形过程中易起皱,具有较大的回弹量。采用回弹补偿法和多道次成形工序对某船用曲面件进行多点成形试验,并通过三维扫描和Geomagic软件对成形精度进行了分析,结果表明:采用回弹补偿法和多道次成形方法可以很好地解决曲线的回弹和起皱问题。

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
