Numerical study on the influenceof interpolator elastic modulus in reconfigurable multipoint forming

Abstract

The elastic interpolator between the pins active elements and the blank leads to increasing the quality of the reconfigurable multipoint formed parts. The paper presents a simulation model based on the presence of a flexible interface in the system assembly. In the first part of the paper are discussed the general aspects of material behaviour laws in the studied reconfigurable multipoint forming system. Then in the paper are presented the simulations results, using finite element approach, regarding the influence of the interpolator elastic modulus, interpolator thickness and pins strokes toward the parts quality. The parts quality is evaluated in terms of springback. The results could lead to the development of these new types of equipments which ensure the decreasing of the cost testing and production.
