Abstract：
|
|
The power spinning of thin-walled shell with special shape is a complicated plastic forming process.Using the 3D FEM model for the process established from ABAQUS/Explicit platform,the influence laws of roller parameters,including radius of roller roundness,roller installation angle and feed rate of roller,on the change of the tangential and circumferential stress and the wall thickness in the power spinning process of the thin-walled shell have been revealed.The results show that the decrease of roller roundness radius or roller feed rate,or the increase of roller installation angle will weaken and even eliminate the metal accumulation in front of the roller,and then will make the plastic deformation and the wall thickness distribution more homogeneous.
