Abstract

The shaping of a rectangular welded sheet assembly by pressurized gas is investigated by finite-element modeling. It is found that, in the formation of a cylindrical dome, the width of the assembly decreases at first and then, after reaching the shell diameter, begins to increase. In other words, the cylindrical shell is deformed practically without thinning.

从矩形焊接组合件上塑造圆柱壳

摘要

通过有限元建模研究了加压气体对矩形焊接板组件的成形。已经发现，在形成圆柱形圆顶的过程中，组件的宽度首先减小，然后在达到壳体直径之后开始增大。换句话说，圆柱形壳体实际上变形而不变薄。
