Research Abstract |
The purpose of this study is to improve the reliability and safety of ships and airplanes. I have developed the real-time prediction technique of the distributed loads on a ship structure or an airplane fuselage based by inverse analysis based on strain distributions measured by fiber-optic sensors. In this study I confirmed good accuracy and stability of this technique for a simple plate model by simulations and experiments. Then I could identify various load distributions on the wing structures made of advanced composite materials in simulation.
