ABSTRACT:
A method of designing an optimum skeleton structure uses a computer to obtain a skeleton structure from a density distribution within a 2 or 3 dimensional design region which is obtained as an optimum shape of a mechanical structure, where the design region is divided into finite elements each having a density D assigned thereto. The method includes the steps of (a) inputting a first reference value D.sub.S of the density D, (b) regarding a point within the design region where an external force is applied as one of starting point candidates, (c) selecting a starting point which is non-selected from the starting point candidates, (d) extending a line from the starting point and passing through the finite element satisfying D.gtoreq.D.sub.S so that the line is as straight as possible, and (e) stopping the extension of the line and regarding the line as a skeleton member when no adjacent finite element satisfying D.gtoreq.D.sub.S exists or when a non-selected starting point candidate is reached. The steps (c) through (e) are repeated until no more non-selected starting point candidate exists.
