波浪中における船の操縦運動シミュレーション（第2報：zig-zag運動とプロペラ逆転停止運動）

摘要

Simulations of zig-zag maneuver and crash astern in regular waves were carried out. The simulation model used for the stopping maneuver takes only wave drift forces into account to usual maneuvering model in still water. On the other hands, the model for the zig-zag maneuver includes wave-induced motion effects in addition to the wave drift forces. In this paper the validity of the methods are confirmed through comparison with free-running model test results in head and beam waves with various wave lengths for SR108 container ship model. It was found that the simulation methods can roughly predict the zig-zag and stopping maneuvers in regular waves, although there is some room for improvement. It may be needed to make more rational hydrodynamic model or improve the calculation accuracy of wave drift forces.%著者は，前報（第1報）において，波浪中における旋回運動の シミュレーション計算結果を水槽試験結果と比較し，計算法の検 証を行った。本論文では，前報の続きとして，規則波中におけ るzig-zag運動とプロペラ逆転停止運動に関する検討結果につい て報告する。 最初に，波浪中におけるzig-zag運動とプロペラ逆転停止運動 に関する過去の研究例をレビューする。
