【Abstract】 A reasonable FEM simulation model for the tube power spinning processes was proposed with respect to the characteristics of the tube power spinning. The processes under different forming conditions were simulated by FEM and the influences of the key process parameters: thinning ratio, roller feedin, roller forming angle and roller radius, on the spining processes were analyzed. The curves of forming taken with different parameters were presented. The forming defects were predicted according to the simulation results.更多还原
