鳍/被动水舱联合减摇理论研究

本文在综合分析减摇鳍与被动减摇水舱两种减摇装置的优缺点的基础上,考虑某些特殊用途的船舶以及一些大型的军用舰艇在全航速下对船舶平衡要求较高的情况,采用了一种优良的全航速下的减摇方案--减摇鳍与被动水舱联合减摇装置.这种减摇装置将减摇鳍与被动水舱有效结合,有效地克服了减摇鳍与被动水舱的缺点,同时也放宽了对鳍静特征数的要求,这对于装有不可收放式减摇鳍的船舶具有实际意义.针对上述联合减摇装置建立了船舶/减摇鳍/水舱的数学分析模型,并进行了分析讨论.通过对一实船的理论计算,结果表明:鳍/被动水舱联合减摇方案与其它减摇装置相比有明显的优越性,这种装置弥补了减摇鳍和减摇水舱具有的缺点,为船舶减摇提供一种减摇的方法.同时,可在此基础上增加装置的功能,达到一定的经济性.

Theoretical Investigation on the Combined Stabilization of the Fin and Anti-roll Tank for Ships

The new stabilization method which is introduced in this paper about fin stabilizer and anti\|rolling tank associated with controlling system is based on the integrated study with regard to the relative merits of the fin stabilizer and anti\|rolling tank. Since some special ships and large\|scale warships are in great need of the stabilization when they are navigated in full\|speed,the fin stabilizer and passive anti\|rolling tank are unied efficiently in this anti\|rolling system,which conquers the shortcomings that the fin stabilizer or passive anti\|rolling tank possesses respectively,and the demand of fin's static characteristic parameters is relaxed. This has practical meaning for the ships with the fixed fin stabilizer. Then the mathematical model of a ship with fin stabilizer and anti\|rolling tank is pressented and analyzed. Finally the theoretical calculation of a real ship is performed and the simulation result has validated the excellent capability of the proposed method that makes up the disadvantages of fin stabilizer or anti\|rolling tank.At the same time,the new function is increased in this system and the definite economical goal is achieved.
