Abstract
Applying the basis vector method to complicated shape optimization problem is examined that it is effective things. But, when actually calculating shape optimization problem or in real optimization system development, many application problems exist yet. In this paper, a flexible basis vector method is applied to the optimization of 3D structure. And examined some problems such as : how to control inside substructures when the boundary shape is changed; how to check the independence of basis vector to each other; and the re-meshing problem when the shape variable is changed. Then proposed calculation algorithm, respectively. In the numerical example, and optimization problem of structure is calculated, the result verify out validity of present methods.
