WATER TANK MODEL MOORING TEST APPARATUS AND WATER TANK MODEL MOORING TEST METHOD
To provide a water tank model mooring test apparatus and a water tank model mooring test method capable of performing a mooring test that is mechanically similar to the real mooring system of an actual machine, corresponding to the water depth and region of an assumed mooring sea area, maintaining the scale of a floating-body structure at a size that does not degrade measurement accuracy, even when there are limitations on the width and depth of a test tank in the case of measuring various data for mooring floating-body structures such as marine structures with mooring cables.SOLUTION: In a water tank model mooring test apparatus used to measure various data when mooring a floating body structure with mooring cables, a mooring simulator 30 is provided which generates an inertia force, a damping force, and a restoring force that are mechanically similar to the mooring system of an actual machine by connecting a main mass body 34b, a sub-mass body 34c, a damping force generator 35, and a recovery force generator 36a to a main cable-like body 37 connected to a model mooring cable 41 connected to a floating body model 10 corresponding to the floating body structure.SELECTED DRAWING: Figure 3
【課題】海洋構造物等の浮体構造物を係留索で係留する際の諸データを計測する場合に、試験水槽の幅および水深の制約があっても、浮体構造物の縮尺を計測精度が劣化しない大きさに維持しつつ、係留想定海域の水深や領域における実機の係留系に対応して、この実機の係留系と力学的に相似な係留試験を行うことができる水槽模型係留試験装置及び水槽模型係留試験方法を提供する。【解決手段】浮体構造物を係留索で係留する際の諸データを計測する場合に使用する水槽模型係留試験装置において、浮体構造物に対応する浮体模型１０に接続される模型係留索４１に接続する主索状体３７に主質量体３４ｂ、副質量体３４ｃ、減衰力発生体３５、復原力発生体３６ａを接続して、それぞれ実機の係留系と力学的相似になる慣性力、減衰力、復原力を発生させる係留模擬装置３０を備えて構成される。【選択図】図３
