Abstract
The multipass V-H rolling process with different vertical roll shape was simulated by explicit dynamic FEM and updating geometric method and the head and tail shape of rolled piece for different pass and vertical roll shape was analyzed. The results show that when using flat vertical roll, the wedge angle appears in tail, but it does not appear when using shape vertical roll , and the length of rolled piece is shorter than that using shape vertical roll, so its elongation is larger; when using shape vertical roll, the head and tail shape of rolled piece changs little as the groove fillet radius of roll changes. At the same time, the calculated head and tail shape of rolled piece for flat vertical roll in different pass is consistent with the measured one when the model material is lead.
