【摘要】 根据钢管张力减径过程的变形特点 ,对五机架张力减径过程进行系统建模 ,利用MARC软件进行三维弹塑性有限元分析 ,得出了钢管在各机架的变形情况 ,为预报产品质量、分析产品缺陷提供了依据。更多还原

【Abstract】 The model of five-stand continuous stretch reducing process was built according to the tube deformation characteristic. The tube deformation on every stand was indicated by the 3-D elastic-plastic finite element analysis with software MARC, which could provide foundation for predicting product quality and analyzing product flaws.更多还原
