摘要

机械膨胀模具在膨胀过程中所经历的应力比管道的屈服强度低约（10.26%）。其次，进行了有限元分析，以研究优化机械膨胀模具设计对成品管形的好处。该研究表明，与原始膨胀模尺寸相比，将膨胀模半径减小（1%）可显著改善管道形状，并降低膨胀模上的应力集中。

Non-linear Analysis of the Expanding Stage in the UOE Pipe Manufacturing Process

stresses, the mechanical expander dies experience during the expansion are about (10.26%) lower than the pipe’s yield strength. Secondly, the FEA was carried out to investigate the benefit of optimising the mechanical expander dies design on the finished pipe shape. This study showed that reducing the expander die radius by (1%) significantly improves the pipe shape compared to the original expander die size and lowers the stress concentration on the expander dies.
