Minimizing dynamic effects while using dynamic codes to simulate binder-set processes

When using a dynamic code to simulate a quasi-static job, the dynamic e ect is a very serious problem, such as in the binder set simulation in stamping process design. Dynamic e ects generally consist of two di erent acting types, oscillation due to the kinetic energy of the blank and additional deformation thanks to the inertial action. For the binder set simulation, the inertial e ect is more apt to change the simulation result due to less-constrained forming of the blank. Light e ect varies the magnitude of blank deformation. Seriousness shall result in the deformation type change of the forming blank, which could make simulating results useless for real-world application. To aim at the dynamic problems, especially in the inertial e ect, several useful and practical ways have been proposed in this paper. Some parameters that we can use to minimize dynamic e ects during a simulation e ectively include: the velocity type of the travelling part, damping, de ning the travelling part and imposing additional loads on the forming blank. Finally, four associated simulation cases have been discussed to show how these enhancing methods can be applied in real stamping production
