Finite Element Simulation of Cold Pilgering Process of TA18 Tubes

Based on DEFORM-3D software,3D Elastic-plastic FE model for cold pilgering of TA18 titanium tubes has been developed.The reliability of the model is validated and this FE model lays a foundation for further researches.Through simulations and analysis of cold pilgering process of tubes under certain conditions,the distribution and variation laws for the velocity field and strain field,and curves of rolling force-stroke have been acquired,which reveal the laws of the cold pilgering process.The research could provide a reference for the optimum design of cold pilgering process.
