Three-roll planetary rolling force simulation based on FEM

Adopting finite element methods,the three-roll planetary rolling force was simulated.The key FEM techniques and methods of the TP2 copper tubes on three-roll planetary rolling were discussed. The FEM models were designed and the rolling force change was given.The results indicated:during the three-roll planetary rolling,the rolling force was changed on the tube cycle direction present 120°distri-bution.The tube shape and the contact area were changed on the planetary rolling which results in rolling force take on wave phenomena.
