Structural optimization techniques such as topology and shape optimizations have been successfully utilized in mechanical industries. it is, however, difficult to create practicable structure, which we can use for the design and development of mechanical products. This paper presents a new hierarchical optimization method, which is integrated based on topology optimization, shape optimization using traction method and a concept of topological derivatives. This method can create a practicable structure, which has simple topology and smooth surface. It is confirmed that the obtained optimal structure is estimated to be 10% lighter than the initial structure, and the proposed method can be useful for the design of practical structures.
