| Abstract: |
| To reduce the time of getting an ideal elliptical heat used in power station through repairing and testing a die repeatedly according to experience,finite element software Deform-3D was used to research the simulation of deformation-heat transfer coupling in hot forming process of elliptical head with the size of Φ1200 mm ×100 mm. The variations of stress,stain,temperature,thickness and strain rate in forming process were gotten,and the forming quality was evaluated from roundness,thinning rate and thermal contraction. The results show that the maximum thinning rate of the elliptical head is 7. 31% ,it is close to the orthographic place; and the inner diam- eter obtained from simulation is 1200. 6 - 1202. 977 mm,it is in the range of inner diameter tolerance required; all the data fit well with the practical dimension data of processing head. |
