Abstract
A thermal mechanical coupled model for High-Speed rail screw spike had been established with the aid of FE software Deform-3D by using rig id-plastic FEM. According to the results of finite element simulation, the metal flowing rules in plastic deforming were discussed. Stress and strain field distribution of Screw Spike were concrete researched. It has important theoretical sense and using values on solving part precision forming and workpiece quality improvement of plat cross wedge rolling.
