大型船舶综合减摇系统的研究

本文在分析船舶的综合减摇问题以及船舶主要减横摇装置的优缺点的基础上,针对船舶的减横摇问题,兼顾船舶的静倾问题,提出了可应用于全工况下的船舶综合减摇系统.综合减摇系统是由减摇鳍、减摇水舱和抗静倾平衡水舱组成的.这种综合减摇系统既综合了鳍与水舱的优点,又克服了减摇鳍和减摇水舱各自的缺陷.以高速滚装船为例,建立了"船舶-减摇鳍-被动式U型水舱"系统的运动方程并进行了计算机仿真.通过对仿真结果的讨论和分析得到如下结论:这种综合减摇系统具有良好的减摇能力;在各种航态下(包括零航速)都能达到减摇要求;综合减摇系统的减摇性能远远好于单独使用减摇鳍和减摇水舱的性能.船舶综合减摇系统的提出为大型船舶的综合平衡开辟了新途径,这种设计方法对大型水面舰船、尤其对有舰载机的船舶及两栖作战舰船的综合减摇具有重要意义.

Research on Integrated Roll Stabilization System for Large Ships

After the advantages and disadvantages of fin stabilizer and anti-roll tank are analyzed respectively in this paper, integrated roll stabilization system, combined fin stabilizer and anti-roll tank with anti-heel tank, is proposed to reduce ship roll under different encountering wave directions and ship speeds. The system can make up the disadvantages which are generated by using the fin st abilizer and anti-roll tank respectively. The ship's roll motion equation contr olled by fin stabilizer-passive anti-roll tank is put forward and simulated. T he integrated roll stabilization system has better roll reducing effectiveness t han the fin stabilizer and passive anti-roll tank under different encountering wave directions and ship speeds. The system proposed in this paper has profound significance in ship anti-roll technology, especial for large ships and small a ircraft carrier.
