本文介绍了直径400mm铝合金球壳的整体液压胀形过程,测定了壳体胀形过程中球壳板的小心挠度变化和板面应变分布,并对板面的应力应变分布规律及壳体的变形特点进行了分析。
In this paper, the overall hydroforming process of aluminum alloy spherical shell with diameter of 400mm is introduced. The variation of the deflection and the strain distribution of the spherical shell during the bulging of the shell are measured. The stress and strain distribution of the shell and the Deformation characteristics were analyzed.
