Multidisciplinary investigation by fluid-structure-motion integrated simulation

Abstract

This study is devoted to realize the flight system based on biomimetic mechanisms by using multidisciplinary numerical simulation that consists of flow simulation, structural simulation and motion analysis. In this paper, the effective motion is investigated to generate sufficient force to make a flight. The flow simulation is carried out by finite difference and finite volume method in overset grid while the structural analysis is conducted by linear elastic simulation with finite element method. The coupled algorithm is constructed from the weak coupling with inner iteration. As a result, it was revealed that the fluid force is increased by the deformation of the object.
