漁船の極限状態における運動に関する研究-IV : マシュー方程式による数値解析

抄録

In the experiments using the self-proppelled model ship, capsizing phenomena were observed after the lurching motion thought to be the low cycle resonance. Concerning these phenomena, the non-linear Mathieu's function was used for describing the rolling motions. The authors solved these equations numerically by means of Runge-Kutta-Gill method and tried to show the agreement of experiments and theory, comparing between the calculated and the measured rolling motions in the experiment. Further, the simulations for the rolling motion of fishing boats due to waves were performed numerically and discussed.
