| Abstract: | The thesis applied 3-D elastic-plastic finite elementmethod to establish single-series element model, consideredthe main facts that influence metal-flow such as configure pat-tem of roll pass, tension action etc. and continous roll modelfor coupling calculation is established by the tension and dis-placement mis-loaded. The distribution of tube wall changeunder different conditions has been analyzed. The reliabilityof model has been verified by contrast of calculation resultsand experiment results, which provided foundation for techni-dal theory study including whole inspect of tension reducing,mills, exploring equipment potential, developing new productand so on. |
| Keywords: | elastic-plastic FEM tension reducing mix-loaded tension distribution |
