圆形焊接弯管的径向变形受力分析

Stress Analysis of Radial Transfi guration of Circular Welding Pipe

圆管段或圆锥管段在端口与其它圆管段或圆锥管段形成角连接时,角连接焊缝处不同管段由于变形的方向不一致而使内应力形成了一定的角度从而使得在径向形成了合力,这个合力阻止径向变形。

The deformation direction of different pipe sections was different at the welding position when the round pipe or cone pipe sections were connected with other pipe sections as angle connections. It caused an angle of the internal stress which finally formed the radial resultant force and had positive function in preventing pipe radial deformation.
