Fixed type pendulum wave energy converter is a kind of movable body type wave energy converter and it was invented by Kondo with Muroran Institute of Technology in Japan. Some researches on this device were carried out experimentally and theoretically, and its high energy conversion efficiency was shown. However, this device was not practical used yet, because the initial cost is so expensive as it needs heavy construction in the sea. And also, it is difficult to keep it safety under the critical weather condition like a typhoon is another main reason. So, as a solution strategy for above problems,Furusawa proposed the uplifting type pendulum wave energy converter. Furthermore Watabe proposed the floating type pendulum wave energy converter (FPWEC) which is moored to the seabed with some lines as another solution. Changing from fixed type device to floating type device, we can expect the reduction of initial costs and emergency measures. Watabe carried out some research on FPWEC, but it is not enough to say that the design method for this device was established.In this paper, we have made a test model of FPWEC for tank test and some tests were carried out as a first step of development for this device.To estimate the performance of this device, we have measured power output and body motion in regular waves.

本研究では,高い精度を有する,渦法による浮体構造物の非線形波浪中挙動解析法の開発を目的に,自由表面下で振動する2次元没水平板の問題に,Random-Wal k法およびCore-Spreading法に基づく渦法計算を適用し,平板に作用する流体力について検討を行った.その結果,Core-Spreading法および物体近傍での渦層モデルを用いることで,これまでの波浪問題に適用されてきたRandom-Walk法に基づく手法より実験結果と近い結果が得られた.
