압출공정 및 제품 향상을 위한 유한요소 해석기법의 적용
FEM Method Application for Extrusion process and Product improvement
초록
It have been proceeded that research of analysis of extrusion process using porthole die. recently it is performed partly through the finite element method in the non steady state that design variables. The subject of this research is integrity improvement of speaker body which is being produced by porthole die extrusion in my country. Extrusion load of speaker case, and welding pressure of billet in the chamber are estimated by the means of rigid-plasticity finite element method. And then extrusion of trial was performed to estimate the validity of FE analysis.
