압력최소화를 위한 자동차용 도어트림의 밸브 게이트 위치 최적화

Abstract

In this study, we decided the valve gate locations to minimize the injection pressure. To automatically build the finite element model of the runner system corresponding to the valve gate locations changed, we developed a runner system automatic modeling module. To solve this design problem, we integrated MAPS-3D, a commercial injection molding analysis CAE tool, using the file parsing method of PIAnO as a commercial process integration and design optimization tool. To obtain an optimal solution sufficiently, we used an orthogonal array as an experimental design available in PIAnO. Using the proposed design approach, the maximum injection pressure has been reduced by 25% compared to the initial one. This design result clearly shows the validity of the proposed design approach.
