Abstract：
|
|
An analysis of spinning quality defect on aluminium sheet taper was carried out and studied based on simulation of spinning by finite element method.The characteristics of spinning on various technical parameters were exhibited and the key factor was searched as guidance for spinning technics for which the spinning tests were developed to validate and optimize the simulated result.It is concluded that multi-abnormity distortions were exhibited in spinning simulation,such as rupture,flange-warp,drape,unstable state and so on.The spinning technics was valuably instituted and optimized.The spinning quality and producing efficiency were improved evidently with the quality defects being avoided.
