先入観のない状態からの機械システムに対する形状・機能の創成的概念設計

抄録

This paper presents methodologies for generating conceptual designs of a structural system, in which structural shapes, inner structural organizations and a functional element are, as much as possible, created without any preconceived information from an element likened to a seed, that is, the initially given detailed information is kept to a minimum. First, a feasible design region initially containing nothing is defined. The entire feasible region which is uniformly filled up with finite elements having extremely low rigidity is here assumed to be a region containing nothing. Then, a seed element grows into an entire structural system in the feasible design region by both creating external shapes and growing inner structures. Next, the design method is advanced so that a functional element of a rotational joint is also simultaneously generated with the structural shapes. Finally, the proposed methods are demonstrated using conceptual designs of industrial robot-like structures having the functions of hanging and transporting an object.
