Background

Observing the morphology of living organisms, you can see that the design that is suitable for each living environment is applied to the living body. Therefore, in this theme, we are working on the development of the structure design technology based on the biological form and the development of the technology enabling manufacture of the structure (shell + rib) reflecting complicated biological forms.

Specifically, we aim to establish efficient design methods based on biological norms and to establish technologies that can quickly produce high strength, lightweight structural members using braiding technology.

Goals

The goal of this theme is to establish 'bioinnovative design technology' integrating the above as one design / manufacturing system.
For that reason,

1. Building a database that stores about 50 types of biometric data(Figure 1)
2. Development of optimum design support system using database
3. Development of integral manufacturing method of rib + shell structure

are set as a development target until the end of FY 2016.

Implementation contents

1. Design database with morphogenesis in biology(Figure 1)

   The biological form is adapted to various environments, and it is optimized form in a sense. We will build a database to use it as a design idea in the design upstream.

2. Optimal design utilizing database

   We will discover a new Pareto front which achieves both weight saving and high strength, and develop efficient optimum design method utilizing the biological form database.

3. Design and manufacturing by braiding technology

   From the result of optimization, we will manufacture mandrels with 3D printers(Figure 2).
   Prototyping with carbon fiber using braided technology(Figure 3,4)。
