| Outline of Final Research Achievements |
We have developed a pressure sensor for measuring the pressure distribution acting on the hull surface of a ship advancing in waves, and a measurement method and data analysis technology using it. The pressure sensor is a affix-type sensor that uses FBG technology, which is one of the optical sensing technologies, and can measure multiple points at the same time. In addition, the developed pressure sensor is attached to one side of the test model at about 330 points, and the pressure distribution at various wavelengths in the head wave (regular wave) is measured to confirm the pressure sensor and measurement / analysis method. Furthermore, the usefulness of this measurement data was confirmed by subjecting the obtained results to a benchmark test of existing theoretical calculation methods including CFD.
