摘要
给出十字型抗纵摇舵的概念,从理论上讨论了十字型抗纵摇舵的水动力作用机理及其对纵摇和垂荡方程的影响。对给定的S175船型,进行了十字型抗纵摇舵的实用化设计,并利用改进的切片理论计算方法(STF法),考察和比较了规则波中不同航速、不同浪向角航行时船舶的纵摇、垂荡的频率响应函数。对抗纵摇舵的减摇效果的理论研究结果表明,新型抗纵摇舵的减摇效果明显,具有良好的工程应用前景。
In this paper, the concept of anti-pitching rudders is given and the hydrodynamic mechanism of anti-pitching rudders and their effects on the ship pitching and heaving motions are theoretically discussed. A practical anti-pitching rudder has been specially designed for S175 ship. Based on the new strip theory （STF method）, the pitching and heaving responses of S175 ships with and without anti-pitching rudders have been numerically calculated and compared. The results presented manifest that anti-pitching rudders are effective in reducing the amplitude of ship pitching motion, and can be practically applied to ship design in the future.
