| Abstract: | Due to the complication of three-layered tube with dense-body and power-body material for nuclear energy field,the finite element numerical simulation software MSC.Marc was used to successfully solve the problem of establishing three-layered tube model.This model could achieve the bending with the slave simulation.Its springback and ellipticity were analyzed.From simulation results,the mould was designed and the experiment was carried out.The experimental results agreed well with the simulation ones,which proved the reliability of the established model.A bending with high forming quality was achieved. |
