Finite Element Simulation of 2014 Al Alloy Plate in Hot Rolling Process
The finite element simulation of the hot rolling process for the 2014 aluminum alloy plate under different processes was carried out by using ABAQUS software. The effects of the reduction amount and the friction coefficient on the stress, the strain, the rolling force and the spread were analyzed. The results show that increasing the reduction amount can make the deformation penetrate into the center of the rolled piece and reduce its residual stress; during the stable rolling stage, the rolling force increases with the increase of the reduction amount,and the friction coefficient has a smaller effect on the rolling force; when the reduction amount is 12, 25, 36 mm(10%, 21%, 30%), the rolling force of the rolled piece respectively are 3400, 4600, 5500 kN; when the other conditions remain unchanged, the spread increases with the increase of the reduction amount, and decreases with the increase of friction coefficient.
