OPTIMAL SHAPE DESIGN METHOD, OPTIMAL SHAPE DESIGN DEVICE, AND OPTIMAL SHAPE DESIGN PROGRAM FOR STRUCTURE

摘要

To provide an optimal shape design method, an optimal shape design device and an optimal shape design program for a structure capable of setting an optimal shape of a structure that can be manufactured by a molding processing technique in a short period of time without depending upon experience or intuition of a designer.SOLUTION: An optimal shape design device 1 for a structure according one embodiment of the present invention includes: a density-structure shape DB 2 for storing data of at least one moldable partial structure shape in each range of a prescribed density distribution; and an information processing device 3 for converting a density distribution of the structure into an aggregate of partial structure shapes, and outputting data of the aggregate of the partial structure shapes as data of the optimal shape of the structure by arranging partial structure shapes corresponding to each density distribution of a structure acquired by a phase optimization calculation with reference to the density-structure shape DB 2.SELECTED DRAWING: Figure 1
