| Abstract: | Based on a three-dimensionally parameterized channel model, the optimal design of the extrusion die was studied via finite element numerical analysis combined with optimization. The objective function is that the average flow velocity of each sub-field of profile cross section at extrusion die exit is equal,and the design variables are the thickness of the entrance of compression zone and the length of parallel zone. An example was provided to illustrate the optimization method proposed above. Results showed that the method proposed in this paper is valid and effective. |
