본 논문은 마그네트 천장크레인 거더에 대한 경량화를 위한 구조최적설계를 수행하였다. 최적화는 ANSYS 소프트웨어를 사용하여 거더의 중량에 대하여 수행되어졌으며, 특히 거더의 상판, 하판, 옆판 그리고 보강판의 두께인 치수에 초점을 맞추었다. 마그네트 크레인의 중량은 처짐, 응력, 고유진동수와 좌굴강도의 제한을 만족하며 약 15%까지 감량되었으며 또한, 구조적인 안전성이 거더의 판넬구조물의 좌굴해석에 의해 입증되었다. 구조최적화로 중량감소에 대해 예로부터 경험적으로 설계된 구조물을 설계하는 것에 매우 유용할 것으로 생각된다. 또한, 본 논문에서는 설계변수들이 목적함수와 상태변수에 미치는 민감도를 평가하였다.

In this study, structural optimum design was applied to the girder of magnet over head crane. The optimization was carried out using ANSYS Code for the deadweight of girder, especially focused on the thickness of its upper, lower, side and reinforced plates. The weight could be reduced up to around 15 % with constraints of its deformation, stress, natural frequency and buckling strength. The structural safety was also verified by the buckling analysis of its panel structure. It might be thought to be very useful to design the conventional structures for the weight save through the structural optimization.

The objective function and restricted function were estimated by the orthogonal array, and the sensitivity analysis of design variable fur that was operated.
