Abstract

Present research deals with an optimal design of the C-type frame of a desktop pressing machine to minimize its deformation which plays an important role in accuracy of the machine. Deformation pattern of the frame is analyzed by the finite element method. Design parameters are defined for the frame to derive an optimal design. Displacement and weight sensitivities of the parameters are analyzed using the method of the parametric study. On the basis of the response curves for the parameters, optimal designs of the frame are proposed. Effectiveness of the optimal design is verified by analyses in the viewpoint of the deformation and weight of the frame. Deformation of the optimized frame without increase of the weight is 87.5 % of the original frame.

탁상용 정밀압입기의 압입정밀도에 영향을 미치는 C형 프레임의 변형을 최소화하기 위한 최적설계 연구를 다루었다. 압입기의 C형 프레임의 기존설계안에 대한 유한요소해석을 통하여 프레임의 변형양상을 분석하였다. 매개변수연구법에 의한 최적설계기법을 사용하여 설계변수가 프레임 변위 및 무게에 미치는 영향을 분석하고 최적설계안을 제시하였으며, 설계변수의 반응 특성에 근거한 구조개선 방안을 제시하고 효과를 입증하였다. 도출된 최적설계안의 C형 프레임은 기존설계안 대비 무게가 증가하지 않으면서 변형이 87.5 %로 감소하는 것으로 나타났다.
