Spline Rolling Analysis Based on DEFORM-3D

Based on the basic theory of rigid-plastic finite element method(FEM),by means of a common three-dimensional finite element analysis software DEFORM-3D,a three-dimensional dynamic FE simulation model of the whole process of spline cold roll forming was established.The results show that the distribution of equivalent stress equivalent strain and the flow laws of metal in spline cold roll forming,which provides a theoretical basis for study on spline cold forming process.
