Abstract：

The simulation of stainless steel tube stagger spinning process was carried out by the finite element software of Deform-3D to reveal the reason of defects of the stagger spun tube. The magnitude,distribution and variation rule of piling and diametral growth defects were analyzed under the different technical parameters. Experiments were also performed to verify the validity of the simulation results. When the working angle of the roller is in the range of 25°-30°,feeding ratio of 0.8 mm·r-1 and reducing rate of 30%,there are smaller and homogenous equivalent stress,smaller bulge and diametral growth as well as steady spinning process. The results will be helpful to the optimization of the tube stagger spinning and direct the practice production.
