Optimization Design of I-Type Plastic Extrusion Die Based on Flow Balance
With the I-type plastic extrusion die for example, the advantages and disadvantages between the traditional design method and optimization design method were compared. The design was studied via finite element numeric analysis combined with optimization, whose objective was the equal average flow velocity of each sub-field of profile cross section at extrusion die. And the optimization design w...
متن کاملOptimization of Axisymmetric Extrusion Die Profiles
In this research, optimization process of axisymmetric extrusion dies is proposed. Plastic zone is analyzed using finite element method in the Eulerian system with flow formulation. The die profiles are defined by Bezier curves with six control points. Two effective functions are considered in this research; standard deviation of the strain rate and the rate of energy consumption during extrusi...
متن کاملNumerical Shape Optimization as an Approach to Extrusion Die Design
Profile extrusion is a manufacturing process used for continuous plastics profiles with a fixed cross section. The key challenge in the development of profile extrusion dies is to design the transition region between outflow and inflow of the die in such a way, that the material velocity at the outflow is homogeneous. At the current state of the art, die design is experience based and time-cons...
متن کاملflow balance of an extrusion die for production of a u-shaped profile
the main objective of an extrusion die is flow balancing as an unbalanced flow causes a distorted product together with residual stress. in this paper a strategy is presented for flow balancing a u-shaped profile with different wall thicknesses. for this purpose, a choker bar is provided at thicker wall to locally restrict excessive flow passing through the thicker section. for optimal design s...
متن کاملConsidering the Soil Effects on Design Process of Performance-Based Plastic Design for Reinforced Concrete Structures
In this research, Performance-Based Plastic Design (PBPD) method has been modified according to the proposed method for considering Soil–Structure Interaction (SSI) effects. In the proposed modified method, based on the existing relationships and in order to maintain the simplicity of the PBPD design method, two important parameters have been modified in the PBPD design method. These two parame...
