OPTIMUM DESIGN SUPPORT DEVICE, OPTIMUM SETTING SUPPORT METHOD, AND OPTIMUM DESIGN SUPPORT PROGRAM

摘要

An optimum design support device for designing a structure in which when a load or displacement is given to a predetermined portion, a desired load or displacement is outputted using elastic deformation in each portion to another portion. The device comprises a functional structure creating section (11) for creating a functional structure (FM), i.e., an organic coupling structure of different function elements, in which initial member arrangement in a design area (D) is varied so that the output load or displacement approaches the desired load or displacement and the overall rigidity of the structure is enhanced, an initial actual shape setting section (12) for determining an initial actual shape (IS) which enables the function of each function element constituting the functional structure (FM) to be realized, and an actual shape modifying section (13) for modifying the initial actual shape (IS) in order that the displacement, load, stress, or strain associated with the desired load or displacement approaches a predetermined target value in a range that each portion of the initial actual shape (IS) is elastically deformed.
