FEM Numerical Simulation on Tube Spinning of Guided Missile Body Based on ABAQUS

ZHAO Teng-lun(China Airborne Missile Academy,Luoyang 471009,China)  
To solve the difficulty of the technical parameters selection in spinning process of guided missile body,a 3D elastic-plastic finite element model is constructed for the guided missile body spinning process based on the elastic-plastic finite element theory,the metal flow in three directions(tangential,radial and axial) and the friction effect are considered generally.With the model,the effect of various technical parameters(including the fillet radius of the roller,the feed velocity,the decrement of the thickness per procedure) on the forming results are studied.
