Abstract：

The ANSYS/LS-DYNA was applied to simulate numerically the roll-pressing process of spirally grooved tube by sphere roller and triangle roller with arc,and the distribution regulation of stress and strain,the regulation of metal flow and the value of roll-pressing force were obtained.Based on the results of simulation,the effect of different roller shape and main geometrical parameters of the tube on roll-pressing force and deformation of wall thickness was analyzed.The reliability of numerical simulation was proved by experiments,and the relation between roll-pressing force and corrugation depth was obtained as guidance.And it provides theoretic foundation for further study on mechanical characteristics during roll-pressing process of spirally grooved tube.
