    Abstract
  • On the basis of the parametric curved-surface tool description and finite element meshing tool description, a curved-surface & element description method for the tool geometric shape model is established. An updated global & local contact search algorithm is introduced. An optimized selection for intersected iterative initial value and a contact judgement rule based on the no-penetration theory is deduced. Then a finite element contact search model for numerical simulation in sheet metal forming processes is set up. The model not only improves the astringency of the finite element numerical simulation, but also enhances the efficiency & stability of the numerical simulation of contact processes. The astringency, efficiency & stability of this model are verified well by calculation and experiment.
