Research on Lift Control System of Single Wing Fin Stabilizer at Zero Speed

Abstract

The technique is a kind of new concept of anti rolling ship at zero forward speed. It is different from conventional ship fin stabilizer that the lift of fin stabilizer based on movement mode of pitching and heaving is produced by initiative swing at zero speed. The lift control system is built according to lift feedback and lift limit. It is undoubtedly another development to introduce lift control to ship roll stabilization at zero forward speed. The simulation of anti rolling effect is researched at the different sea wave condition about significant wave height is 1m and 2 m, wave direction angle is 90* . And the anti rolling effects are 78.30 percent and 56.92 percent respectively. It is proved that the designed system could be satisfied with the need of anti rolling ship at zero speed. This research is supported by the science and technology research project of Education Department of Heilongjiang Province (11544044).
