ANALOG COMPUTERによる船体動揺のSIMULATIONについて(日本航海学会第41回講演会)

抄録

This is a study on the estimation of responsive characteristics of a ship motion in waves by the use of an analog computer. In this paper, according to the rolling test and the curve of statical transverse stability of the ship, each coefficient of the equation of motion for the ship rolling was determined on the model ship shown in Fig.1 and Table 1. Then, the equation of motion was simulated on the analog computer. The block diagram is shown in Appendix A-1. As to the equation of motion in eq. (1) and (2), the responsive characteristics of the ship motion were calculated by the analog computer. The results of the calculation are compared with the experimental results which were obtained through the tank experiment for the above mentioned model ship. It is shown that the calculated results agree with the experimental values. Then, as an example of this method in practical use, the responsive characteristics of rolling motion of the fishing boat are calculated by this method and discussed.
