摘要：

铝合金半球形件为航空常见结构件，其特点是零件壁厚较薄、变形量较大，通常采用多工步方法成形。为了提高产品质量和生产效率，提出采用在铝合金坯料表面覆不锈钢的方法进行粘性介质拉深成形。采用有限元软件ANSYS/LS-DYNA对铝合金半球形件覆不锈钢粘性介质拉深成形过程进行了数值模拟，分析压边力和粘性介质压力对成形过程的影响，得到不同压边力加载曲线条件下成形试件壁厚分布、法兰区材料向变形区流入量及粘性介质压力场的变化规律，并进行试验验证。结果表明，在合适变压边力加载曲线条件下，采用覆不锈钢方法进行铝合金半球件粘性介质拉深成形，可以提高铝合金的均匀变形能力，能够直接成形出该零件。

The hemispherical aluminum alloy part is commonly used in the field of aviation. Due to its characteristics of thin wall and large deformation, it is usually formed through multi-step process. In order to improve the quality of the products and production efficiency, the viscous medium drawing technology was proposed to coat hemispherical aluminum alloy part using stainless steel. The above process was simulated numerically using the finite element software ANSYS/LS-DYNA. The effect of blank holder force (BHF) and viscous medium force on the viscous medium drawing process was analyzed, and further, the regularity of forming part thickness distribution, flange area materials inflow to the deformation area and viscous medium force field were obtained under different BHF load curves. Simulation results were verified through the experimental results. The results show that viscous medium drawing the hemispherical aluminum alloy part can improve the aluminum alloy deformation ability and form parts directly under an appropriate variable BHF curve.
