Abstract：

According to the shape requirements of P tube and design ideas of cold roll forming, the forming technology of P tube was designed by professional design software COPRA．Then, the calculation model under actual working conditions was set up, and a simulated deformation was conducted by the deformation technology module of COPRA．Whether the maximum of sheet strain could exceed the strain limit or not was taken as the basis for determining the rationality. According to the results of the simulation deformation, the allocation scheme of the variable quantity of the angle and the amount of compression was improved, and the forming rolls were designed．On that basis, the geometric model of P tube was established, and the whole forming process was simulated by ABAQUS．By analyzing the simulation results，the springback angle was compensated for the forming surface of the last pass．The results show that the computer aided design technology can optimize the forming process, predict the forming defects and improve the design reliability．
