船舶零航速减摇鳍升力仿真研究

应用船舶减摇鳍在零航速时进行减摇，与传统减摇理论有着本质的不同。为了研究船舶零航速减摇鳍在零航速时产生升力的过程，以Weis- Fogh理论为基础，建立了零航速减摇鳍升力模型，对哈尔滨工程大学研制的NJ5型减摇鳍升力模型进行了仿真研究，并应用计算流体力学软件，针对NJ5型减摇鳍进行了数值计算，结果表明数值计算与仿真结果一致，为以后进行水动力试验以及控制规律的进一步研究打下了基础。

Simulation on Lift Generation of Ship Antirolling Fin at Zero Speed

The antirolling with ship antirolling fin at zero speed is different from that of the conven-tional antirolling theory of ship. In order to study the process of lift generation of antirolling fin at zero speed, a lift generation model of antirolling fin was built at zero forward speed based on the theory of Weis-Fogh mechanism, and the lift generation model of NJ5 antirolling fin developed by Harbin Engi?neering University was studied by simulation. For NJ5 antirolling fin, a numerical calculation was made using the CFD software. The result shows that the numerical calculalion result is accordant with the simulation one. The method lays the foundation of conducting hydrodynamic test and researching controlling rule further.
