実船を用いた船体応答計測について-II : 周波数応答関数の推定

抄録

A long time testing on board with a hull response system has been put into practice, in order to clarify the hull response of fishing boat while crusing and fishing. In this paper, we analyzed the records of waves and ship motions which were obtained in the testing, and compared the observed values with the theoretical ones by New Strip Method about charactalistics of ship motions. It was confirmed that the wave height of a record and double amplitude of roll and pitch angles were found to follow Rayleigh distribution. The observed the values for response function also are nearly equal to the theoretical ones by New Strip Method. On the other hand, it is necessary to analyze the response function according to the hypothesis of short waves.
