The Size Optimization Design of Crane using the Table of Orthogonal Array and Finite Element Analysis

직교배열표와 유한요소해석을 이용한 크레인의 치수최적설계

The correlation between the object function and the design parameter is shown on this paper by using the characteristic function for tile mixed result of the structure analysis. tile buckling analysis and the table of orthogonal array according to the original crane's dimensional change. About the above two object functions, the effective of design change according to the change of design parameters could be estimated. Also, the crane's weight is reduced up to 20.58 percent maintaining the structural stability according to the thickness of plate.
