摘要
超级油轮(VLCC)由于其自身惯性大、方形系数大等特点,其操纵性与一般的大型船舶存在很大差异,因此对其操纵性特别是波浪中的操纵性进行研究就显得尤为重要。目前国内鲜有研究人员对不同波陡、初始浪向角下VLCC波浪中的操纵性进行详细和深入研究,本文采用一种新型自航模系统的操纵性试验和数值模拟的方法对不同波陡规则波下VLCC波浪中的操纵性能进行了研究。在试验中,通过改变波浪参数,重点研究分析了不同波陡、初始浪向角对VLCC操纵性的影响,并与数值模拟进行比较,结果吻合良好。
Due to large inertia moment and block coefficient, maneuverability is one of the most concerned problems for VLCC. Especially the maneuverability of VLCC in waves becomes more and more important. However, there are still very few researches which deal with the effects of incident waves. Actually different wave steepness and initial angles of wave incidence should be taken into account in detail. Therefore, free running model test and numerical simulation of maneuverability of VLCC of a 320 kDWT are presented in this paper. The influences of initial angles of wave incidence and wave steepness on the maneuverability have been studied. According to the comparisons, numerical simulation by the proposed method agrees with test results with fairly high accuracy.
