| Abstract: | According to the deforming peculiarity of drawing of nuclear RPV cylinder forging ,four quantitative indicia were defined to determine the quality of deformation in this paper as :uniformity of internal deformation ,deforming ratio at the end of forging,distortion ratio of hole and drawing efficiency The influence of V anvil angle to deformation was studied for mandral drawing of nuclear cylinder forging with Upper flat and Lower V\|Shaped anvils by means of moire and FE method It is found that 110° is a rational anvil angle according to the four quantitative indicia. |
| Keywords: | nuclear forging mandral drawing moire FEM |
