机械密封用焊接金属波纹管非线性应力分析

Nonlinear stress analysis on welded metal bellows of mechanical seals

针对机械密封用焊接金属波纹管的特点 ,考虑了波纹管内外缘焊菇的影响 ,从而建立新的力学模型 ,并利用有关文献提出的方法 ,计算了焊接波纹管在受轴对称载荷时的非线性应力。

Welding mushroom s always produce a great im pact on the stress of diaphragm. In order to investigate the nonlinear problem of welded metal bellows under axial load,a new mechanical m odel has been proposed for the special configuration of welded m etal bellows and analyzed according to the reference[5～ 6 ].
